• ✨ Audio intelligence add-ons: Beyond raw transcripts, Gladia offers diarization, automatic language detection and code-switching, sentiment analysis, named entity recognition, word-level timestamps, summarization, and any-to-any translation.
• ✨ Telephony and communication stack support: The API is tuned for SIP and common telephony protocols at 8 kHz, and works with WebRTC and popular communications platforms, fitting easily into existing voice pipelines.
• ✨ Developer-first experience: REST and WebSocket endpoints, language-agnostic integration, lightweight SDKs, playground, status page, and Discord-based community support keep integration quick and transparent.
