Data transmission system including mechanism for correcting errors in a dialed number

摘要

A data communication system (20) for transmitting data on a telecommunication link. The data transmission system includes a modem/digital signal processor (26) that is programmed to detect alert tones that precede an informational message indicating a problem with a placed call. Once the alert tones are detected, a speech recognition program converts the spoken informational message into one or more text strings which are analyzed for instructions on how the call should be handled. <IMAGE>
