Voice agents live or die on the pause before a reply. Synthesis starts in about 200 milliseconds and runs at 3.3 times real time, which leaves the budget where it usually belongs: your model.

Narration is the one job where a voice has to hold up for hours rather than seconds. 163 of the 244 voices here carry the narration tag, the largest group in the catalog, across English, Hindi and nine other Indic languages.

Latency
Where the latency actually goes
Synthesis starts in roughly 200 milliseconds and runs at 3.3 times real time, so a five second reply renders in about a second and a half. That is usually the smallest part of a turn. Speech recognition and your language model typically account for more, which is worth measuring before optimising the voice layer.
Choosing a voice for sustained conversation
Nine voices carry the Voice Agent tag and 195 the broader conversational tag. For agents the useful filter is not tone but language: Hindi and English sit in the same family, so one voice can serve a caller who moves between them. Tamil, Telugu and the other Indic languages each need a voice recommended for that language.
Interrupting cleanly
Barge-in is handled in your orchestration rather than here, but generation speed decides whether it feels natural. Because audio begins in about 200 milliseconds, cutting a reply short and starting a new one does not register as a gap. A slower engine turns every interruption into an awkward pause.
Streaming transports
Three options exist. Synchronous HTTP waits for the complete clip and is wrong for live turns. SSE streams audio back as it renders. WebSocket suits sessions where text arrives incrementally from a language model and you want playback to begin before the sentence is finished. Most agent builds use WebSocket.

AI Voices for IVR & Telephony
IVR voices need to survive a compressed phone line, not just sound good in a browser. These output ulaw and alaw directly, generate in roughly 200 milliseconds, and handle Hindi and English in the same prompt.
AI Voices for Customer Support Automation
Support calls reach people who are already inconvenienced, often on a poor line. These voices favour clarity over character, hold steady across renders, and move between Hindi and English the way callers actually do.
AI Voices for Voice Chatbots
Web chat is unusual because the visitor reads and listens at once. These voices suit an unhurried delivery, begin playing in about 200 milliseconds over WebSocket, and cover twelve languages from one integration.
AI Voices for Live Narration & Streaming
Generation runs at 3.3 times real time, so audio renders faster than it plays and the buffer stays ahead. First audio arrives in about 200 milliseconds over SSE or WebSocket.
Conversational Voices
One hundred and ninety five voices carry the conversational tag, 84 percent of the catalog. Streaming is what makes them feel live: audio begins playing before the sentence has finished rendering.
Indian English AI Voices
One hundred and four voices carry an Indian accent, more than twice any other group. They handle English words inside Devanagari sentences without changing register, which is how Indian English is actually spoken.
