VoIP: Voice over IP is a protocol to transmit voice over standard IP networks.
Skype and all other voice messengers use VoIP. And if you are wondering
how VoIP relates to IVR, well, you can set up an IVR application that works
over VoIP and you wouldn't need phone lines. People can call in using their
VoIP software and you won't even touch the telecom networks!
SIP: Session Initiation Protocol is a way to make Voice over IP (VoIP) calls.
SIP is used extensively in VoIP applications to establish calls.
DTMF: Dual Tone Multi-Frequency, or "touch tone", input means input via
the phone's numeric keypad.
Text To Speech (TTS): Converting a text to audio. There are many
text-to-speech engines available, and different voices too??”e.g. Male
and Female.
Speech Recognition: The process of understanding spoken words and
converting them to text. For IVR applications, it's best to limit speech
recognition to a few words per input.
IVR Infrastructure: Hosted or Owned?
The easiest way to run a voice application is to find a company that hosts
VoiceXML-based IVR applications.
