Abstract: A client device such as a laptop, PDA or mobile phone includes means for converting speech input by a user into DTMF tones which are transmitted over a voice channel to an interactive voice response (IVR) telephony application. For example the application may provide access to a users bank account details and require a tone input as part of the interactive dialogue with the user. The speech may be converted to text before conversion into DTMF tones. An allowed response feature may also be provided which converts the users response to a known valid response of the IVR application. A language conversion feature may further be provided to allow a person to speak to an IVR application which operates in a different language to that of the user. The speech may also be converted to ASCII text or WAP format.
