Speech-to-text and audio intelligence API for production voice products
Stream audio over WebSocket for live captioning or submit files via REST for batch transcription, supporting MP3, WAV, FLAC, Opus, and most other formats.
Automatic, accent-sensitive language detection across 100+ languages, including code-switching for conversations that move between languages mid-sentence.
Speaker diarization, named entity recognition, PII redaction, sentiment analysis, and summarization, each billed only when you enable it.
Feed transcripts directly into a large language model, either Gladia-hosted or a model you bring yourself (BYOM), to generate summaries and structured outputs.
Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
