Abstract
The present invention involves a method that allows a user of a Push-to-talk over Cellular PoC system to select more flexibly the mode of transmitting. By means of the present invention, the user of a PoC terminal (UE1) is able to send text during an ongoing PoC session to a PoC server (PS) which transcodes the text into speech before transmitting it to the other participants (UE2) of the PoC session. Additionally, the method allows a speech-to-text transcoding act, for example, in order to add subtitles to a video clip that is shown during a video-PoC session. Further, the method allows speech-to-speech transcoding in order to replace the sender'"'"'s own speech with another speech or voice during a PoC session. In addition to the text-to-speech, speech-to-text and/or speech-to-speech transcoding, the PoC server (PS) may be arranged to translate the received data into another language and to send the translated data to the recipients or back to the sender.
