Gladia

From async to live streaming, our API empowers your platform with accurate, multilingual speech-to-text and actionable insights

Gladia gives developers a single API to transcribe and enrich audio so voice products can turn conversations into structured, actionable data. Async speech-to-text handles recordings and long-form audio, Real-time STT delivers sub-300ms latency for live applications, and an Audio Intelligence layer adds diarization, translation, and other enrichment on top of transcripts.

The models behind it are Solaria-1, described as a universal STT fluent in any language, and Solaria-3, which the site says reaches a 9.6% word error rate on real English audio with its strongest gains across English, French, German, Spanish, and Italian. Public benchmarks compare Gladia with eight providers, including Deepgram, AssemblyAI, and ElevenLabs, and a blind test lets you upload audio and vote on transcripts with model names hidden. Use cases include meeting assistants, contact centres, voice agents, and content and media. A newer product, GladiaFlow, offers real-time dictation across your desktop with no code, the main non-developer entry into this music and audio tool.

The site has a Pricing page, sign-up, and demo request, but no plan details on the homepage. Try the blind test with your own audio before committing.
