Gladia
Gladia is an audio transcription and intelligence API built for real-time and async speech processing in agent pipelines. It supports multilingual transcription, speaker diarization, live streaming, and audio intelligence features like named entity recognition and summarization—all bundled into a single per-hour rate without add-on fees. The API handles pre-recorded and live audio with a unified interface, making it popular for meeting intelligence and voice agent post-call analytics. Pricing starts free (10 hrs/mo), with PAYG at $0.20/hr async and $0.25/hr real-time; enterprise plans include custom models and fine-tuning.
Solid choice for most workflows
You need low-latency, multilingual transcription with diarization and intelligence for live voice agents and meeting bots that handle global calls without dropping quality on accents or code-switching.
Excellent accuracy in EN/FR/ES/IT, solid for rare languages; partials stream fast for UI but prioritize finals for precision; handles noisy calls well but may need custom vocab for jargon.
You want post-call analytics for voice agents or CCaaS, extracting entities, summaries, and insights from async audio without juggling multiple vendor APIs.
Transcribes 95% faster than alternatives per benchmarks; channel-based diarization shines for stereo calls, auto-diarization good but not perfect on overlapping speech.
Gladia edges on multilingual (100+ langs + code-switching) and bundled intelligence at lower flat pricing; Deepgram leads on raw English speed.
Pick Gladia for global/international agents needing translation, NER, and summaries without add-on fees.
Pick Deepgram for ultra-low latency English-only or custom model needs.
Partials vs Finals in Real-Time
Partials stream fast (~300ms) for live UI but have lower accuracy; finals are precise but delayed—configure to prioritize finals unless UI demands immediacy, or use both.
