An HMM database stores a large number of speech patterns from many speakers to facilitate speech recognition from a diverse clientele. Modern IVR systems use natural language speech recognition to interpret callers’ questions; some also rely on human agents to aid the speech recognition mechanism. A customer (typically a corporation) can either purchase an IVR platform to use at a speciﬁed location or pay a monthly charge for an IVR supplied by a telecom operator. IVR systems are often criticized as being difﬁcult to use and unresponsive to callers’ needs.
Steps 5 and 6. SSP2 modiﬁes the terminal proﬁle by associating Phone 2 with UPT1 and forwards the successful registration acknowledgment to UPT1. Steps 7 and 8. Concurrent with Step 4, the SCP sends a deregistration message to SSP1. SSP1 modiﬁes the terminal proﬁle by removing UPT1 from Phone 1’s record. With the above registration and call delivery procedures, a UPT user may access telecommunications services with a unique UPT number. 9 Interactive Voice Response Techniques The services described in the previous sections can be signiﬁcantly enhanced with the Interactive Voice Response (IVR) techniques [Pec95].
The calling party may add more members during the conference call. In dial-in teleconferencing, a subscriber books the meeting in advance (through a telecom operator website) and speciﬁes a conference name, the number of participants, date and time, and the duration 44 TELECOMMUNICATIONS SERVICES of the conference. Conference calls are most commonly used in business, as they are ideal for large group conferences such as sales meetings and staff meetings, workshops, or brainstorming sessions.
