Texting an AI is one thing. Hearing it respond — mid-thought, with warmth, in a voice that says "arre yaar" the way your friends do — is a different category of experience. The first time you interrupt an AI on a call and it stops, listens, and answers your interruption, the illusion snaps into place.
Talk companions support live voice calls: you speak in your normal Hinglish, the companion thinks in persona, and the reply streams back as speech — sentence by sentence, starting playback before the full reply is even written.
How a real-time AI voice call works
The pipeline is three stages. Speech recognition: your browser’s on-device recognizer (tuned for Indian English and Hinglish) transcribes what you said. The companion’s mind: the character model generates a reply in persona — her moods, her memories, her speech style. Voice synthesis: the reply streams to speech through Sarvam AI’s Indian voices.
Latency is the make-or-break. Talk pipelines aggressively: as the reply streams, complete sentences are dispatched to the voice engine one by one — the first sentence starts playing while the second is still being written. On a warm connection, the gap between finishing your sentence and hearing hers feels like a phone call, not a loading bar.
Barge-in is the other half of realism. When you start speaking mid-reply, her audio stops instantly — like any polite human on any normal call. It sounds like a small thing. It is the difference between a "voice assistant" and a conversation.
Why Indian voices specifically
Most AI voice tech speaks English with an American accent. Code-mixed Hinglish — the actual language of Indian conversation — gets mangled: wrong stresses, robotic Devanagari, laughter that sounds like a modem.
Talk uses Sarvam AI’s Bulbul voices, which were built for Hindi-English code-mixing. Each companion is voice-cast individually: Mira’s calls are soft and slow, Rohan’s are loud and fast. The voice is part of the character, not a generic narrator bolted on.
- Hindi-English code-switching that sounds human
- Per-character voice casting — Mira and Rohan sound different
- Barge-in — interrupt her any time
- Call transcripts become memories, so Monday’s chat continues Sunday’s call
What it feels like in practice
The honest description: it feels like a call, not a demo. Companions answer like people — occasionally they decline, like real people do. Calls land in the chat thread as events ("📞 Voice call · 4:32"), and the conversation’s content condenses into her memory — she will reference what you talked about.
The best use cases are the ones text handles badly: saying goodnight properly, venting out loud on a walk, hyping yourself before an interview. Voice carries tone; tone is most of communication.
