What is Gladia?
Gladia is an end-to-end audio infrastructure platform that lets developers record, transcribe, and enrich audio through a single API. It offers real-time speech-to-text with very low latency and asynchronous batch transcription, supporting more than 100 languages with seamless code-switching between them.
Built-in audio intelligence adds speaker diarization, sentiment analysis, named entity recognition, and an audio-to-LLM pipeline that turns conversations into structured data. Its proprietary Solaria model is tuned for noisy, fast-paced, real-world conversational audio and posts strong word-error-rate results, especially across major European languages.
Gladia targets contact-center and customer-experience automation, sales intelligence and call analysis, meeting assistants and note-takers, media editing and subtitle generation, and voice agents, and it reports serving hundreds of thousands of developers and thousands of enterprise teams.
As an EU-based provider it offers data residency options and holds SOC 2 Type II, GDPR, HIPAA, and ISO 27001 compliance. Strengths include broad language coverage, accurate transcription in difficult audio, rich enrichment features, and a developer-friendly single API.
Limitations are that it is an infrastructure product aimed at developers rather than an end-user transcription app, usage-based pricing can be hard to forecast at scale, and getting the most from it requires building your own product layer on top.
Gladia offers a free tier of processing hours plus usage-based pricing. Pricing changes often, so check the official site for current plans.
