The present invention relates to a method for transferring information from a sender to a recipient during a telephone call between a sender communication apparatus and a recipient communication apparatus. The present invention relates to communication apparatus arranged to perform the method.
Having a phone call between two or more call participants may encounter various problems. For example, during a telephone call one participant might have perfect signal on its telephone but still be subjective to a noisy environment. One solution to this problem is to by various methods improve the volume of the sound emitted by the telephone of the participant being in the noisy environment. However, this solution is not sufficient for some situations. Moreover, this solution might in the long run inflict damage to the hear ability of the participant.
Hence, there is a need for improvements in connection with receiving a telephone call at a noisy environment.
It is an object to at least partly address the problem discussed above.
According to a first aspect a method for transferring information from a sender to a recipient during a telephone call between a sender communication apparatus and a recipient communication apparatus is provided. The method comprises detecting, by the recipient communication apparatus, that the recipient is subjected to a noisy environment; converting a voice message, originating from the senders voice and recorded by the sender communication apparatus, into a text message; and displaying, at a display of the recipient communication apparatus, the text message to the recipient.
By detecting that the recipient communication apparatus is in a noisy environment and converting the voice message of the sender into text to be presented to the recipient increased quality of the information transmitted during the telephone call is achieved. Moreover, the activation of voice to text conversion may be performed without the need of sender integration or approval. Furthermore, the activation of voice to text may be made dynamic based on the noise level of the environment.
The act of detecting may comprise comparing a measured noise level with a predetermined threshold noise level.
The act of detecting may comprise activation of a button, switch or slider on the recipient communication device.
The act of detecting may comprise determining if an expression expressed by the recipient and recorded by the recipient communication device belongs to a predefined set of expressions related to the recipient's inability to hear or understand spoken information during the telephone call.
The act of detecting may comprise determining if the recipient is repeatedly putting the recipient communication device to the ear of the recipient.
The method may further comprise indicating by sound and/or vibration, induced at the recipient communication device, that the act of converting is initiated. A simple but yet effective way of making the recipient aware of the voice to text has been activated is provided.
The method may further comprise playing, at a loudspeaker of the recipient communication apparatus, the voice message to the recipient. By both displaying the text message and playing the voice message increased quality of the information transmitted during the telephone call is achieved.
The method may further comprise detecting a language spoken by the caller; and translating the text message into another language than the language spoken by the caller.
The act of converting may be performed in the recipient communication apparatus. A method wherein all acts may be performed in a single communication apparatus is hereby provided. This simplifies the communication in the telephone communication link. Moreover, this makes it possible for implementing the method even in the case of the sender communication device does not have the ability to perform voice to text conversion.
The act of converting may be performed in the sender communication apparatus. The risk of losing data in the radio communication between the communication apparatuses is limited.
According to a second aspect a non-transitory computer-readable recording medium is provided.

The sender and/or recipient communication apparatus 10, 20 may be a stand-alone communication apparatus, such as a mobile phone, a laptop, a smart watch or a tablet comprising a radio module. Alternatively, the sender and/or recipient communication apparatus may be an aggregate of interconnected personal communication devices. In this context a personal communication device shall be construed as device configured to communicate with one or more other personal communication devices within a personal area network. Typically the personal area network is a wireless personal area network, WPAN, carried over a wireless network technology such as INSTEON, IrDA, Wireless USB, Bluetooth, Z-Wave or ZigBee. The reach of a WPAN varies from a few centimeters to a few meters. A non-limiting example of an aggregate of interconnected personal communication devices is an aggregate comprising a mobile phone and a headset, the mobile phone and the headset being interconnected via Bluetooth. Another non-limiting example of an aggregate of interconnected personal communication devices is an aggregate comprising a mobile phone and a smart watch, the mobile phone and the smart watch being interconnected via Wireless USB.
A telephone call may be established between the sender communication apparatus 10 and the recipient communication apparatus 20. In this context a telephone call shall be construed as a telephone communication link established between the sender communication apparatus 10 and the recipient communication apparatus 20. The telephone communication link may be established directly between the sender communication apparatus 10 and the recipient communication apparatus 20. Alternatively, the telephone communication link may be established via the base station 30. The radio module 11 of the sender communication apparatus 10 is configured to establish a telephone communication link with the radio module 21 of the recipient communication apparatus 20. Alternatively, the radio module 21 of the recipient communication apparatus 20 is configured to establish a telephone communication link with the radio module 11 of the sender communication apparatus 10. The telephone communication link may be a wireless telephone communication link, a wired communication link or a combination thereof. The wireless telephone communication link may be established using any known wireless telephone technology. As non-limiting examples 3G-, 4G- or 5G-mobile telecommunications technology, or any IP-protocol over WiFi may be used. The wired telephone communication link may be established using any known wired technology.
During a telephone call, a voice message, originating from the voice of a user of the sender communication apparatus 10, is recorded by the microphone 12 of the sender communication apparatus 10. The user of the sender communication apparatus 10 will in the continuing be referred to as the sender. During a telephone call the voice message is then typically sent to the recipient communication apparatus 20 to be played by the loudspeaker 23 of the recipient communication apparatus 20. However, as has been discussed above in the background section sometimes the user of the recipient communication apparatus 20 will have difficulties to hear the played voice message due to being subjected to a noisy environment. The user of the recipient communication apparatus 20 will in the continuing be referred to as the recipient.
The radio module 21 is configured to establish a telephone call with another communication apparatus, e.g. the sender communication apparatus 10.
The noise detecting module 24 is configured to detect if the communication apparatus is located in a noisy environment. In this context noisy environment shall be construed as an environment where the sound level is above a predetermined threshold. According to embodiments the sound level shall be above the predetermined threshold for a predetermined time in order for the environment to be considered as being noisy. According to embodiments the environment is considered as being noisy as long as the sound level is above the predetermined threshold. The noise detecting module 24 may be embodied in many different ways. The noise detecting module 24 may be implemented in hardware, in software or in a combination thereof.
As a non-limiting example, the noise detecting module 24 may be a noise level determining module configured to determine if a measured noise level is above a predetermined threshold. The noise level may be measured by means of the microphone 22 of the recipient communication apparatus. IN this context, the noise level determining module may be configured to detect if the communication apparatus is located in a noisy environment by utilizing data from a background noise reduction algorithm. Typically, background noise reduction is performed by taking advantage of that the microphone 22 of the recipient communication apparatus 20 comprises a primary microphone and a secondary microphone. The primary microphone is aimed to the recipient's mouth to record the voice of the recipient, whilst also picking up any noise from the surrounding environment. The secondary microphone is located elsewhere, typically on the back of the recipient communication apparatus and does not pick up so much speech but mainly noise from the surrounding environment. By comparing the signals from the primary and secondary microphones the noise level of the surrounding environment may be established.
Alternatively or in combination, the noise detecting module 24 may be a button, switch or slider configured to the activated by a recipient. The button, switch or slider may be implemented as a virtual button, switch or slider on a touch display of the recipient communication device. The button, switch or slider may be implemented as a physical button, switch or slider. The recipient may thus simply activate the button, switch or slider upon being subjected for the noisy environment.
Alternatively or in combination, the noise detecting module 24 may be a voice interpreter configured to determine if an expression expressed by the recipient and recorded by the microphone 22 of the recipient communication apparatus belongs to a predefined set of expressions related to the recipient's inability to hear or understand spoken information during the telephone call. Non-limiting examples of expression belonging to the predefined set of expressions are “what did you say”, “I did not hear you”, “what” and “please, repeat”.
Alternatively or in combination, the noise detecting module 24 may be implemented as determining how often a near ear detector is activated. Detecting that the recipient repeatedly puts the recipient communication device 20 to her ear indicates that the recipient has problems hearing the voice message. Thus, this may be indicative that the recipient communication apparatus 20 being located in a noisy environment.
The voice to text converting module 25 is configured to convert an, during the telephone call, incoming voice message into a text message. The voice to text converting module 25 is configured to convert the incoming voice message in response to the recipient communication apparatus 20 being located in a noisy environment. The voice to text converting module 25 may be embodied in many different ways. The voice to text converting module 25 may be implemented in hardware, in software or in a combination thereof. According to a non-limiting example, the voice to text converting module 25 is implementing the T.140 protocol for multimedia application text conversation.
The display 26 is configured to display the text message. The display 26 may further be configured to display an activation message indicating that a conversion mode has been activated. In this context the conversion mode shall be construed as a mode in which the voice to text conversion is active. According to embodiments just as been discussed above the voice to text conversion may be performed in the recipient communication apparatus. However, according to embodiments the voice to text conversion may also or in combination be performed in the sender communication apparatus, see below.
The loudspeaker 23 may be configured to play the incoming voice message simultaneously as the display 26 is displaying the text message. In this context simultaneously shall be construed as that the receiver of the voice and text messages shall regard the messages to be presented to him at the same time. According to a non-limiting example, simultaneously may be construed as within a time delay that is less than 100 ms, preferably less than 50 ms, more preferably less than 10 ms.
The loudspeaker 23 may further be configured to play an activation message indicating that the conversion mode has been activated. Such a played activation message may be a beep or the like. The playing of the activation message may be in addition to the activation message displayed by the display. The playing of the activation message may be instead of displaying the activation message on the display.
Alternatively or in combination, indication of entering into conversion mode may be performed using a tactile module 27 of the recipient communication apparatus. The tactile module 27 is configured to provide the recipient with tactile feedback. Hence, the entering into conversion mode may be indicated using vibration.
The processor 27 is arranged to perform a variety of acts or processes. Especially the processor 27 may arranged to perform any of the acts, fully or in part, mentioned above or below in case the act is implemented in software. For example, the processor 27 may be constituting a part of or fully the noise detecting module 24 and/or the text converting module 25. The processor 27 may comprise a single processing unit or multiple processing units. In case of multiple processing units each processing unit may be specialized in performing one or more acts of processing.
The memory 28 is arranged to buffer and or store data being processed by the processor 27. The memory 28 may comprise a single memory or a plurality of different memories. In case of a plurality of memories each memory may be specialized in storing one or more kind of data.
Alternatively or in combination, the recipient communication apparatus 20 may be configured to receive the from the voice message into the text message converted text message over the telephone communication link. If so, the conversion of the voice message into the text message may be performed by a voice to text converting module (not shown) of the sender communication apparatus 10. Alternatively or in combination, the conversion of the voice message into the text message may be performed by a voice to text converting module (not shown) of the base station 30 or the like used in establishing the telephone communication link. In case of receiving an already converted text message the text message may be generated according to the T.140 protocol for multimedia application text conversation. The text message may then be sent using Text over IP, ToIP. The ToIP is designed around the ITU-T T.140 real-time text presentation layer protocol (defined for H.32× multimedia services). T.140 allows real-time editing of text e.g. by using ‘backspace’ and retyping. T.140 is based on the ISO 10646-1 character set that is used by most IP text specifications and uses the UTF-8 format. Transport of ToIP uses the same Real-time Transport Protocol (RTP) as VoIP and Video-over-IP. The text is encoded according to IETF RFC 4103 “RTP Payload for Text Conversation”. ToIP is a means of providing a real-time text service that operates over IP-based networks. It complements Voice over IP (VoIP) and Video over IP.
