Indic Voices

bulbul:v3 provides 37 voices spanning 11 Indian languages (bn-IN, en-IN, gu-IN, hi-IN, kn-IN, ml-IN, mr-IN, od-IN, pa-IN, ta-IN, te-IN). Pass the voice ID as the voice parameter and the target language. The default voice is shubh. An unrecognized voice falls back to the recommended voice for the request's language (for example ratan for en-IN, ta-IN, mr-IN and gu-IN, shubh for the rest).

Cartesia Voices

sonic-3.6 (Cartesia Sonic 3.6) speaks 44 languages with native-quality Hindi and Hinglish. Pass a featured handle (skylar, default) or any public Cartesia voice UUID as voice, plus a base ISO language code (en, hi). An unrecognized non-UUID handle falls back to skylar.

The live public library is paginated — do not treat the 16 featured aliases as the full set:

curl "https://api.callmissed.com/api/v1/models/sonic-3.6/voices?q=hindi&limit=50"
curl "https://api.callmissed.com/v1/audio/voices?model=sonic-3.6&q=skylar" \
  -H "Authorization: Bearer cm_YOUR_KEY"

GET /api/v1/models/sonic-3.6/voices/{id}/preview streams Cartesia's own pre-recorded sample (no synthesis, no credit charge). Neither listing endpoint synthesizes or bills.

Query params (both listing endpoints): q (search, max 200 chars), language (base code such as hi), gender (masculine / feminine / gender_neutral; male / female also accepted), limit (1–100, default 50), starting_after (a voice id from the previous page). GET /v1/audio/voices takes model=sonic-3.6 (the default and the only accepted value; any other returns 400).

{
  "object": "list",
  "model": "sonic-3.6",
  "data": [
    {
      "id": "voice-uuid",
      "handle": "skylar",
      "name": "Skylar",
      "gender": "feminine",

    }
  ],
  "has_more": true,
  "next_page": "…"
}

handle is set only for the featured aliases below (otherwise null); pass either the id or the handle as voice on POST /v1/audio/speech. preview is null when a voice has no sample. When has_more is true, pass the last voice's id as starting_after to fetch the next page.

If the upstream library is briefly unreachable, the first page answers 200 with the featured aliases below and an extra "degraded": true field instead of failing, so a voice picker still renders and every returned voice remains usable for synthesis. The field is absent on a normal response — treat its presence as "this is the short list, retry later for the full library". A request carrying starting_after is not degraded: pagination returns 502 so you keep the page you already have.

Featured aliases (stable handles, also valid UUIDs in the library):

skylar · daniel · jacqueline · katie · cathy · caroline · ronald · carson · jameson
gemma · archie · riya · arushi · siya · parvati · kabir

riya, arushi, siya, parvati, and kabir are native Hindi speakers (pair with "language": "hi"). Browse the full library in the console Voices page, the Playground, or Talk.

Other TTS providers also expose voices via the same POST /v1/audio/speech endpoint — aura-2-en (40 English voices, default luna), aura-2-es (10 Spanish voices, default aquila), deepgram-aura-2 (90 voices across English, Spanish, German, French, Dutch, Italian, and Japanese, default thalia), deepgram-aura-1 (12 legacy English voices at half the Aura-2 rate, default asteria), and gpt-4o-mini-tts (alloy, ash, ballad, coral, echo, fable, nova, onyx, sage, shimmer, verse, marin, cedar). See Credits & Rate Limits for per-model pricing.

Flux TTS Voices (managed Voice Agent only)

Deepgram Flux TTS is a voice-agent-first model. It is not available on the POST /v1/audio/speech endpoint — it is offered only through the managed Voice Agent (see the Voice Sessions API), selectable with tts_engine: "flux", where synthesis is turn-based, prosody carries across turns, and it is billed inside the per-minute voice rate. It provides 36 English voices (American, British, Indian, Irish, Australian, Singaporean and Filipino accents); the default is priya, an Indian-accented English voice, and an unrecognized voice falls back to the default.
