Why teams choose Soniox over Cartesia for Malayalam

Built for Malayalam, not just English.

Soniox delivers production-grade accuracy in Malayalam and 60+ languages from one streaming model. It understands fast, informal, accented speech in Malayalam, and handles mixed-language phrases, spoken codes, and alphanumerics with precision.

"It just gets the words right, any language, any accent, any context. That’s what accuracy is supposed to look like."

Tony Wang,
Cofounder & Chief Revenue Officer at Agora

Cartesia’s Ink 2 streaming model supports English only, so Malayalam audio falls back to the separate ink-whisper batch model and gives up real-time streaming.

Real-time translation for Malayalam.

Soniox returns Malayalam transcription and any-to-any translation from a single stream, in 60+ target languages, so your app works for 8 billion people without bolting on extra services.

"It’s so fast, captions appear before people even finish talking. Zero lag. No buffering. Nothing."

Dag-Inge Aas,
Head of AI at Tana

Cartesia provides transcription only, with no translation in or out of the stream.

Know who’s speaking in Malayalam, live.

Soniox knows when someone’s speaking, when they’ve stopped, and who’s talking, with built-in real-time speaker separation, sentence boundary detection, and turn-taking awareness.

"Soniox knows who’s speaking and when each thought ends. The real-time transcripts read like true dialogue, not data dumps."

Adam Strom,
Co-Founder & President at Mobius MD

Cartesia has strong built-in turn detection, but speaker diarization is still listed as coming soon.

One API. Everything built in.

Malayalam transcription, any-to-any translation, speaker separation, mixed-language support — all from a single model, endpoint, and call. Production-ready from day one.

Cartesia is built for low-latency English voice agents, but multilingual support, translation, diarization, and customization aren’t available in one stream.

Trusted by teams building global voice products

Developers choose Soniox for accuracy in Malayalam speech

Malayalam is spoken by 38 million people worldwide — primarily in India, with speakers around the world. Soniox delivers production-ready transcription and translation for Malayalam, handling regional accents, code-switching, and real-world audio conditions. Cartesia Ink 2 streams English only, so Malayalam isn't supported in real time.

Cartesia is fast and accurate for English voice agents, with built-in turn detection. But in real time it transcribes English only, has no translation, and lacks diarization today. Soniox offers one API that transcribes and translates Malayalam (and 60+ others) with high accuracy and smooth real-time performance, so your app instantly works worldwide.
