AI Speech-to-Text & Audio Intelligence API
Comprehensive Overview
Real-Time Speech-to-Text API
Gladia provides a speech-to-text API that converts audio into text instantly. Users can transcribe live conversations or uploaded recordings. This helps developers build meeting assistants, voice agents, and transcription tools.
Multi-Language Transcription
The platform supports transcription in more than 100 languages and accents. Users can transcribe multilingual conversations accurately without switching tools. This is useful for global teams, customer support, and international applications.
Speaker Identification (Diarization)
Gladia automatically detects and separates speakers within audio recordings. Users can identify who spoke each part of the transcript easily. This improves clarity in meetings, interviews, and podcast transcripts.
Word-Level Timestamps
The API generates timestamps for each spoken word in the transcript. Users can navigate to exact moments in audio or video files quickly. This feature helps with subtitles, editing, and content indexing.
Developer-Friendly API Integration
Gladia provides REST and WebSocket APIs that developers can integrate quickly. Users can add speech recognition features into applications with minimal setup. This simplifies development of voice-based AI products.
Real-Time Speech-to-Text API
Gladia converts audio into text in real time with low latency. Developers can build applications that respond instantly to spoken input. This capability is useful for voice assistants, meetings, and customer support systems.
Multi-Language Transcription
The platform supports over 100 languages and regional accents. Users can transcribe conversations even when speakers switch languages. This enables global voice applications and multilingual communication tools.
Speaker Identification
Gladia uses diarization to identify and label different speakers. Users can clearly understand dialogue structure in meetings or interviews. This makes transcripts easier to analyze and review.
Word-Level Timestamping
Each word in the transcript includes an exact timestamp. Users can generate subtitles or jump to important parts of recordings easily. This improves audio editing and video caption workflows.
Developer Integration & Scalability
The API is designed for developers building voice-enabled applications. Users can integrate transcription features using simple API calls. The platform scales automatically for real-time or large-volume audio processing.
