Open the CIPO recordAbstract From the Canadian patent
A speech-responsive voice messaging system provides a hierarchically-simple speech user interface (UI) that enables subscribers to specify mailboxes passwords and the like by spoken word. Results are recognized as good bad or question- able according to a set of quality thresholds. Based upon the outcome of the quality evaluation a caller is navigated through speech UI menus. In response to repeated failures of recognition the system automatically transfers to a DTMF UI. The speech and DTMF UIs overlay each other seamlessly for utilization of desired functions in response to mapping of candidate results.

Why it's free to use
- Filed March 23, 1998 and granted January 14, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 23, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 23, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
