What is Gladia?

Gladia provides a powerful Speech-to-Text (STT) API that enables platforms to accurately transcribe audio, both asynchronously and in real-time. It leverages its proprietary Solaria ASR model, which is designed to be universal, precise, and fluent across over 100 languages.

This tool is ideal for businesses and developers building voice-enabled applications, contact center solutions, sales enablement platforms, meeting assistants, and media editing tools.

Gladia emphasizes performance with sub-300ms latency for real-time transcription and offers flexible, usage-based pricing to support scaling without significant infrastructure burden. Gladia differentiates itself with advanced features like code-switching for multilingual conversations, speaker diarization, word-level timestamps, and add-ons such as sentiment analysis, summarization, and chapterization. It also prioritizes data privacy and compliance, being GDPR, HIPAA, and AICPA SOC Type 2 compliant, ensuring audio data is never used for model retraining.
