A system and method allows a user to hear text-based e-mail messages (as well as sound files such as .WAV files) to be played over an ordinary telephone. A user may respond to such messages with voice commands to generate reply messages, or reply sound files as well as input other e-mail commands (e.g., forward, delete, save, and the like). Possible voice commands or responses which may be generated in response to a played message or input prompt are determined in advance. Voice input signals are then compared to this limited list of possible responses (or "grammar") and the system generates a list of guesses as to which response has been spoken. Confidence levels are assigned to these guesses based upon the relative match between the actual reponse and the possible expected response. If the confidence level is above a dynamic threshold value, a match between the spoken response and the corresponding possible response is determined. |
