How to change the speaker voice

The speaker parameter lets you choose a specific voice for the speech output.

Speaker Selection

Specify the speaker using the speaker parameter in your request. It is an optional parameter — if omitted, the API uses the default voice (shubh for bulbul:v3, anushka for bulbul:v2).

Available Voices — Bulbul v3

Bulbul v3 offers 30+ natural-sounding voices:

Male: shubh (default), aditya, rahul, rohan, amit, dev, ratan, varun, manan, sumit, kabir, aayan, ashutosh, advait, anand, tarun, sunny, mani, gokul, vijay, mohit, rehan, soham

Female: ritu, priya, neha, pooja, simran, kavya, ishita, shreya, roopa, tanya, shruti, suhani, kavitha, rupali

Production-Recommended Speakers (Bulbul v3)

Speakers are evaluated by Critical Error Rate (CER) — the percentage of words with critical pronunciation errors. Lower CER = higher reliability.

Recommended Speakers by Language

Not all speakers perform equally across all languages. Always use these language-specific picks over arbitrary selection:

Top picks: priya & ishita (best female — use across Hindi, Telugu, Kannada, Tamil, Marathi, Gujarati, English) · mani (best male overall, Punjabi) · shubh (best male for hi, te, kn, od, ml) · ratan (best male for en, te, kn, ta, mr, gu).
