The present invention is related to providing a reminder of a mute selection to a user of a telephony device. In particular, the present invention is directed to providing a reminder of a mute feature selection in response to detecting a voice signal.
Telephony devices often provide a mute selection feature. The mute selection feature allows the user of a telephony device, such as a telephone or video telephone, to deactivate the microphone on the local device. Accordingly, by activating the mute signal, a user can conduct private conversations while continuing to receive audio signals from other telephony endpoints that are parties to a call. The mute function can also be selected so that typing, rustling papers or other noises are not transmitted to other endpoints. Although typically used in conjunction with a speakerphone function, many telephones also allow muting of a handset microphone through selection of a mute feature.
The selection of a mute feature is usually accomplished by pressing a mute feature button on the user's telephone. Selection of the mute feature button typically deactivates the speaker phone microphone and/or handset microphone of the user's telephony device. In addition, a static indicator light is activated while the mute feature is on.
Oftentimes, participants in telephone conferences activate the mute feature in order to conduct private sidebar conversations. The mute feature may also be selected in order to avoid adding extraneous noise to a conference call. While the mute feature is activated on a communication device, the user or users of that communication device are still able to hear the voices of other parties contributing to the conference call. However, it is not uncommon for such a user to forget that the mute feature has been activated when that user is asked a question or that user decides to make a comment. As a result, a user may speak, intending to add comments to the telephone conference, without unmuting the phone. This problem is particularly prevalent during conference calls where most participants have their phones on mute.
Voice activated devices have been used in various context. For example, voice activated audio recorders are available for conserving storage space for voice data. In addition, voiceover IP (VoIP) telephony devices often do not send data packets if it is determined that a user of the device has not spoken in order to conserve bandwidth. However, it would not be desirable to simply deselect a mute feature in response to the detection of voice or other audible signals, as doing so would make the mute selection feature incapable of performing its primary function, which is to prevent conversations or other noise at an endpoint from being transmitted to other endpoints of a call.
The present invention is directed to solving these and other problems and disadvantages of the prior art. In accordance with embodiments of the present invention, a mute feature selection reminder is generated in response to the detection of a voice signal at a telephony endpoint on which a mute feature has been activated. The mute feature selection reminder may be in addition to a mute feature selection indicator that is activated upon selection of the mute feature.
In accordance with embodiments of the present invention, the mute selection reminder comprises a flashing light that activates in response to the detection of speech at the communication device while the mute feature is activated. In accordance with still other embodiments of the present invention, the mute selection reminder may comprise an indicator light that is in addition to a mute feature selection indicator light. In accordance with still other embodiments of the present invention, the mute feature selection reminder may comprise an audible reminder. In accordance with still other embodiments of the present invention, the mute feature selection reminder may include both visual and audible indications.
Additional features and advantages of embodiments of the present invention will become more readily apparent from the following description, particularly when taken together with the accompanying drawings.

At step 308, a determination is made as to whether a mute feature of the communication device 100 has been selected. For example, in accordance with embodiments of the present invention, a mute feature may be selected by hitting the mute function button 144. If it is determined that the mute feature has not been selected, the process returns to step 304, and the microphone continues to be enabled.
If the mute feature has been selected, the microphone is disabled (step 312). As used herein, disabling a microphone generally comprises disabling the transmission or provision of audible signals local to the communication device 100 that are picked up by a microphone associated with the communication device 100 to the other communication device or devices with which the communication device 100 is engaged in a call. As can be appreciated by one of skill in the art, a mute feature may be selected by the user of a communication device 100 so that the user can conduct private conversations with another person at the location of the communication device 100. A mute feature may also be selected by the user of a communication device 100 to prevent noise, such as noise from typing, the rustling of papers, or other ambient noise, from interfering with audible information being provided by a user of another communication device. In general, while a mute feature is enabled, an indication of such status may be provided by the user, for example through the illumination of a mute indicator lamp 144. Alternatively or in addition, a mute selection message may be displayed by the display 140.
At step 316, a determination may be made as to whether a voice signal is detected at the location of the communication device 100. Detection of a voice signal may comprise operation of a voice activity detector implemented by instructions executed by the processor 216. As can be appreciated by one of skill in the art, voice activity detectors are known, for example in connection with IP telephones in order to conserve bandwidth. More particularly, voice activity detectors such as may be used to suppress the sending of packets that do not contain voice data can be used in connection with the detection of a voice signal to provide a mute feature selection reminder.
In accordance embodiments of the present invention, the voice activity detection function is performed in connection with the receipt of voice information local to the communication device 100 by an audible user input 204. For example, a handset microphone 112, speakerphone microphone 120, or a microphone provided as part of a 5 headset may be used to provide audible information collected from the location of the communication device for analysis by a voice activity detection application 248 running on the processor 216. Furthermore, it should be appreciated that an audible user input 204 may be operative to provide such a signal for analysis by a voice activity detection application 248 or function, even while the mute feature is activated and preventing such 10 audible information from being transmitted to the other communication device or devices associated with a call (i.e., while the selection of the mute feature has disabled the audible user inputs 204). Moreover, it should be appreciated that voice signals that may be received by the communication device 100 from another communication device over a telephony channel as part of an in-progress call are not used to determine whether a voice signal is present for purposes of activating the mute selection reminder.
If a voice signal local to the communication device 100 is detected, a mute feature selection reminder is activated (step 320). The mute feature selection reminder may be provided in various ways, using one or more outputs. For example, the mute feature selection reminder may comprise operating the mute feature selection lamp 148 in a 20 flashing mode. Alternatively or in addition, other indicator lamps, such as the message waiting lamp 160 may be flashed or illuminated to provide a reminder to the user that the mute feature has been selected. As yet another alternative, a dedicated mute feature selection reminder lamp 164 may be illuminated, either steadily or in a flashing mode. A display 140 may be used to display a textual message or otherwise provide a mute 25 selection reminder. As still another example, various provided visual outputs 212 may be operated in combination, for example in a coordinated fashion, to visually alert and remind the user that the mute feature has been selected. In accordance with still other embodiments of the present invention, one or more audible user outputs 208 may be used to provide a reminder to the user that the mute feature has been selected. For example, an 30 audible user output 208, such as the speakerphone speaker 116, may be used to provide a beep, tone or voice reminder that the mute feature has been selected. In accordance with still other embodiments of the present invention, one or more audible user outputs 208 may be used in combination with one or more visual user outputs 212 to provide a mute feature selection reminder to the user. As can be appreciated by one of skill in the art from the description provided herein, a mute feature selection reminder in accordance with embodiments of the present invention can assist in preventing a user from attempting to provide comments or other audible input as a participant in a call while the mute feature is selected.
After activating a mute feature selection reminder at step 320, or after determining at step 316 that a voice signal has not been detected, a determination may be made as to whether the mute feature has been deselected (step 324). If the mute feature has not been deselected, the process may return to step 316, and the microphone (i. e., the audible user inputs 204) may continue to be disabled. If the mute feature has been deselected, the microphone (i.e., the applicable audible user input or inputs 204) may be enabled (step 328).
In addition, it can be appreciated from the present disclosure that embodiments of the present invention do not automatically disable the mute feature in response to detection of a voice signal. That is, embodiments of the present invention do not interfere with one purpose of a mute feature provided as part of a communication device 100, which is to enable private, sidebar conversations, while a call is in progress.
