Abstract:

Informational text is provided to a mobile terminal capable of being coupled to a mobile communications network. Digitally-encoded voice data is received at the mobile terminal via the network. The digitally-encoded voice data is converted to text via a speech recognition module of the mobile terminal. Informational portions of the text are identified and made available to an application of the mobile terminal. In one configuration, speech recognition quality can be improved by extracting the informational text from the near-end speech, and comparing to the text obtained from the received voice data. In another configuration, an analog signal that originates from a public switched telephone network is received at an element of a mobile network. Speech recognition is performed on the analog signal to obtain text that represents conversations contained in the analog signal. The analog signal is encoded to form digitally-encoded voice data suitable for transmission to the mobile terminal. The voice data and the text are then transmitted to the mobile terminal.
