摘要:
A mobile communication device (100) includes a vocoder (104) for vocoding speech (500) received at the mobile communication device. The parameters output by the vocoder are used to generate a voicing quality metric (208). The voicing quality metric is used to provide feedback to the user of the mobile communication device by various feedback modalities including visual (114), audible (108), and tactile modalities (118) to indicate when the user should speak louder to overcome ambient noise. The voicing quality metric is also used by other communications equipment (304, 312) to decide if communication activity is needed.
摘要:
A voice channel data processor 207 and corresponding method 600 operable in a wireless communications unit's 200 receiver and transmitter to facilitate data transmission on a voice channel includes an encoder 301 for encoding data traffic as a transmit voice frame having a predetermined vocoder parameter and inserting the transmit voice frame into a stream of transmit voice frames with voice traffic and further includes a decoder 303 for parsing a stream of received voice frames to obtain a vocoder parameter for each, comparing the vocoder parameter for each received frame to the predetermined vocoder parameter, routing the received voice frame for processing as data traffic when the comparison is favorable, and otherwise routing the received voice frame for processing as voice traffic.
