RECATOOLS Verdict

Deepgram is one of the strongest speech APIs for developers: fast, accurate, per-second billing, and a coherent stack for building voice agents, now with an APAC headquarters in Singapore and growing Southeast Asian language support. Watch the headline prices — the cheapest streaming rate is a limited-time promotion — and the $200 credit is one-time rather than a monthly allowance. Its latency claims are its own. An excellent choice for transcription and real-time voice products; benchmark your own audio and languages before committing.

What we found

Deepgram is a voice AI company that sells speech-to-text, text-to-speech and voice-agent APIs to developers and enterprises. Its Nova-3 models transcribe live and recorded audio in many languages, including Malay, Thai, Vietnamese, Indonesian, Tagalog, Tamil, Mandarin and Cantonese, with specialised versions for fields such as medicine and pharmaceuticals; Flux is a streaming model built for voice agents that detects when a speaker has finished, available in English and, since April 2026, ten languages, with Deepgram putting end-of-turn latency under 400 milliseconds. On the speech side it offers Aura-2 voices and Flux TTS, generally available since August 2026, and a Voice Agent API ties listening, a language model and speech together. Add-ons cover diarization, redaction, entity detection and keyterm prompting, and enterprises can self-host models or use an EU endpoint, with SOC 2, HIPAA and PCI compliance.

Deepgram was founded in 2015 by Scott Stephenson and others from dark-matter physics research, and is based in San Francisco but works remotely. It raised a $130 million Series C at a $1.3 billion valuation in January 2026, led by AVP, and in August announced an Asia-Pacific headquarters in Singapore after an investment from EDBI, citing 96 per cent growth in APAC API requests. It says more than 200,000 developers and 1,400 organisations use it, including NASA, Twilio and Cloudflare.

Pricing is per second of audio. Pay-as-you-go accounts start with a $200 one-time credit, needing no card. Batch Nova-3 costs $0.0043 a minute; streaming Nova-3 is $0.0048 on a limited-time promotion against a regular $0.0077, and Flux $0.0065. Text-to-speech runs $0.015 to $0.045 per 1,000 characters and voice agents from $0.05 a minute. Growth plans start at $4,000 a year in prepaid credit with up to 20 per cent savings, and Enterprise is negotiated.

Deepgram suits developers building transcription and real-time voice products, including in Southeast Asia.
