What is Speechmatics?
Speechmatics is an enterprise-grade speech-to-text API designed for developers and businesses that require exceptional accuracy and speed. It provides the foundational technology to power your applications with real-time transcription, translation, and voice AI, reliably converting spoken audio into structured text at a global scale.
Key Features
⚡️ High-Performance Real-Time Transcription Get final transcripts in under one second. Speechmatics is engineered for low-latency performance without compromising precision, enabling you to build truly interactive and responsive voice experiences, from live captioning to real-time agent assistance.
🎯 Unmatched Real-World Accuracy Achieve over 90% accuracy on real-world audio. Our models are rigorously trained on diverse datasets that include various accents, dialects, and noisy environments. This ensures you receive reliable, high-quality transcripts you can trust, even in challenging conditions where other systems may falter.
🌍 Extensive Global Language Support Reach users across the globe with support for over 55 languages. The API is built to handle multilingual conversations, automatically identifying the spoken language and even managing code-switching within a single audio stream. This allows you to scale your product internationally with a single, unified API.
⚙️ Flexible and Secure Deployment Deploy where it makes the most sense for your business. Speechmatics offers both a secure, scalable cloud API and on-premise options for organizations with strict data sovereignty, security, or compliance requirements. This flexibility ensures you can meet your architectural needs without sacrificing performance.
Use Cases
Contact Centers: You can transcribe and analyze customer calls in real-time to provide live agent assistance, automate quality assurance, and identify customer sentiment. This immediate insight helps improve agent performance and overall customer satisfaction.
Media & Broadcasting: Automatically generate highly accurate live captions and subtitles for broadcasts, virtual events, and video streams. This makes your content instantly accessible to a global and hearing-impaired audience, enhancing engagement and compliance.
Healthcare Technology: Streamline clinical workflows by integrating voice AI that accurately transcribes patient-physician conversations into electronic health records (EHRs). This reduces the administrative burden on medical professionals, minimizes documentation errors, and allows them to focus more on patient care.
Why Choose Speechmatics?
Speechmatics delivers a distinct advantage by refusing to compromise on the critical pillars of speech-to-text technology.

Superior Performance in Real-World Conditions: Our internal benchmarks show that Speechmatics’ real-time transcription produces significantly fewer errors than major competitors, including Microsoft, Assembly AI, and Deepgram. The models excel in noisy environments and with diverse accents, providing a level of reliability that is essential for enterprise applications.
True Enterprise Readiness: Beyond performance, Speechmatics is built for enterprise integration. With features like on-premise deployment, speaker diarization, custom dictionaries for industry-specific jargon, and robust security compliance (SOC2, GDPR, HIPAA), you have the control and flexibility needed to build and scale secure, professional-grade voice features.
