Speech-to-text and voice intelligence APIs for developers
Choose pre-recorded transcription for files, a realtime API for live streams and voice agents, or a synchronous endpoint for short clips and dictation.
Layer summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts without building your own models.
AssemblyAI-TTS-1 is trained on real phone calls for natural, low-latency speech, targeted at IVR and voice-agent use cases.
Flagship models emphasise exact transcription, speaker labels and native code-switching across many languages, supported by published benchmarks.
Low-latency video, voice and AI-agent APIs for developers
Drop-in SDKs for Web, iOS, Android, Flutter, and React Native deliver sub-100ms audio/video with active speaker detection, screen share, chat, polls, Q&A, and a pre-call lobby.
Compose speech-to-text, LLM, and text-to-speech providers into an agent pipeline with VAD and turn detection, then run it server-side on VideoSDK's managed infrastructure.
Ship low-latency interactive streams with audience chat, polls, live captioning, RTMP out, HLS for large audiences, and WHEP/WHIP protocol support.
Record composite or per-participant audio and video tracks with custom layouts and encryption, and send files straight to your own S3, GCP, or Azure bucket.
