Gladia is an advanced audio-intelligence platform that empowers developers and businesses to convert spoken audio or video content into high-quality text — supporting real-time and asynchronous transcription workflows. Whether you are building a live voice-agent, powering call centers, transcribing podcasts or meetings, or generating subtitles for media content, Gladia provides a robust API designed for accuracy, scale, and global multilingual support.

With support for over 100 languages and a strong focus on accent robustness, Gladia handles everything from common global languages to under-represented ones. Its real-time speech-to-text model delivers low-latency transcription (under 300 ms), enabling real-time applications such as voice agents, call-center integration, or live captioning. For media files and pre-recorded sessions, the asynchronous transcription mode can quickly convert hours of audio into text, with word-level timestamps, speaker labels, and optional translation.

Gladia also offers advanced “audio intelligence” capabilities beyond plain transcription. Speaker diarization allows the tool to distinguish between different speakers in a conversation, which is useful for meetings, calls, or interviews. Transcripts carry precise word-level timing metadata, ideal for subtitles, indexing, searchability, or generating captions. Custom vocabulary support helps ensure domain-specific terminology (technical, medical, financial, etc.) is transcribed correctly. Noise reduction, VoIP and telephony compatibility (including 8 kHz audio) make Gladia reliable even for low-quality or compressed audio such as phone calls.

The API is developer-friendly — with REST or WebSocket interfaces, lightweight SDKs, and scalable infrastructure that eliminates users’ need to manage underlying compute resources. Pricing is usage-based, making it accessible for small projects and scalable for enterprises. For organizations needing compliance and data protection, Gladia offers secure hosting and supports enterprise-grade workflows.

Because Gladia combines real-time transcription, multilingual coverage, speaker handling, and flexible integration, it serves as a comprehensive “backbone” for voice-first applications — from customer support platforms to media pipelines, global voice agents, subtitle generation, and more. By transforming audio into actionable, structured text, Gladia enables teams to leverage previously untapped voice data, unlock insights, and build scalable voice-enabled services.
