Other objectives, features and advantages of the present invention will appear from the following detailed disclosure, from the attached dependent claims as well as from the drawings.
The above, as well as additional objects, features and advantages of the present invention, will be better understood through the following illustrative and non-limiting detailed description of preferred embodiments of the present invention, with reference to the appended drawings, where the same reference numerals will be used for similar elements, wherein:
The mobile communication apparatus is capable of presenting themes. A theme in a mobile communication apparatus is a feature used to provide a preferred appearance to a user interface layout. A theme can affect characteristics of a layout, background color, fill and border characteristics of a field, as well as text attributes for labels and/or text. A mobile communication apparatus capable of presenting themes normally provides a set of themes which the user can select according to her preferences at the moment. However, in the present invention the layout of the user interface according to the themes is extended to the audio domain, as will be described below.
The processor 102 is arranged to generate an audio signal in response to a theme, which can be set directly by a user, or by an application executed on the apparatus. Further, the theme can be set by a received message comprising information about which theme to set, or the entire characteristics of a new theme to be set. The theme can also be set in correspondence to a contact associated with an action performed by the apparatus, e.g. a contact accessed by the user in a contact database (not shown) of the apparatus 100, e.g. a phone book, or an incoming or outgoing phone call or message from/to a person associated with an item in the contact database.
The audio signal can comprise a speech signal, which can be generated by text to speech conversion or by voice manipulation, which is performed by the processor 102. The theme includes voice characteristics for speech of the speech signal. For example, when a certain person associated with a contact item calls, a certain theme is set, which comprises voice characteristics, e.g. the particular characteristics of a cartoon character, wherein the name in the contact database is output through text to speech conversion and with a “cartoon voice”, and then can either incoming or outgoing speech signal, or both, of the phone conversation be voice manipulated to sound like the cartoon voice. Another example is a received text message from a person associated with a contact item associated with a theme comprising the voice characteristics of a science fiction character, wherein the text message is converted to speech with the science fiction voice characteristics, and the message is output as speech through the user interface 104. Any combination of the above described features can be set in the themes. According to an embodiment of the present invention, it is also possible to send the audio signal and/or the theme to another subscriber, or to a server in a telecommunication network. For example, a text message to be sent or received can comprise a tag related to text to speech by certain voice characteristics, such that a given voice style can be reproduced. Also other audio features than speech and voice styles can be employed within the audio theme concept, and theme management depending on other parameters. A theme can be activated by a timing signal, e.g. provided by a clock or calendar in the apparatus. For example, when a call is performed when the calendar indicates out of office or vacation, the sound of seagulls and waves can be introduced as a background sound, or when a message is received, comprising a tag indicating that the sending person is in a meeting, a huge sigh is played. The concept of themes tied to association with a contact item is here described in relation to themes comprising audio. However, the concept of themes tied to association with a contact item can be utilized for any theme, e.g. presenting visual effects, background colors or images, adapting applications, etc., when reading messages from a particular contact, viewing calendar events which includes the contact, playing games with the contact, talking to the contact, chatting with the contact, etc.

According to an embodiment of the present invention, a network operator or other third party company handling a theme server 224 could offer a theme provision function. For example a network operator may have a theme server 224 supporting a feature where the theme provider may provide themes and the users may send a theme request from their mobile communication apparatuses 208-22 to the theme server 224. This theme server 224 automatically may place people sending a similar request to the theme server 224 into “theme groups” or “theme rooms”. Further, themes in the theme server can be created or edited by any of the users of the theme group or members of the theme room according to a special service, where a user or member send a message comprising theme characteristics to the theme server 224.
The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
