What does Gladia do?
Gladia provides speech-to-text technology through a developer-friendly API. It converts audio to text with high accuracy, supporting both asynchronous file processing and real-time streaming. The service handles over 100 languages and is optimized for telephony and voice applications, making it suitable for businesses that need reliable transcription at scale.
The API offers two main modes: asynchronous transcription for pre-recorded audio files and real-time streaming with sub-300ms latency for live conversations. What sets Gladia apart is its multilingual code-switching capability, which accurately transcribes conversations where speakers switch between languages. The service integrates with popular communication platforms like Twilio and Vonage, and works with voice agent frameworks such as Vapi and LiveKit.
This tool is particularly valuable for developers building customer support systems, meeting assistants, sales enablement platforms, and voice-based AI agents. Companies in contact center operations, media production, and business process outsourcing use Gladia to add accurate transcription to their applications without managing complex audio processing infrastructure.
