Nova-3 Realtime

by Deepgram

Nova-3 is Deepgram's most advanced speech-to-text model, built to transcribe difficult real-world audio accurately in both streaming and batch modes. Deepgram describes it as the first voice AI model to offer real-time multilingual transcription, following speakers who switch between English, Spanish, French, German, Hindi, Russian, Portuguese, Japanese, Italian and Dutch in a single conversation. It also supports many languages individually, including Hindi. On Deepgram's numbers, Nova-3 reaches a median word error rate of 6.84% on streaming audio, a 54.2% reduction against the next competitor at 14.92%, and 5.26% on batch audio. Keyterm prompting lets developers boost up to 100 domain-specific terms at request time without retraining; Deepgram cites a veterinary customer that saw a 625% improvement in keyterm recognition. It fits live captioning, voice agents, contact centers, drive-thru ordering, emergency response and medical or legal transcription, anywhere low latency and accurate handling of jargon, names and numbers matter.
