Low-latency AI voice API for multilingual, multi-speaker conversations
Speechmatics offers Speech-to-Text (STT) and Text-to-Speech (TTS) APIs built for the real world, handling background noise, overlapping speakers, accents, and technical vocabulary. The technology provides high accuracy across 55+ languages, with real-time and batch processing, and flexible deployment options (cloud, on-premise, hybrid, offline). It's used by businesses for use cases like AI voice agents, live captioning, contact center analytics, and legal transcription. The company emphasizes security, compliance (ISO 27001, GDPR, HIPAA, SOC 2 Type II), and customization, with custom models and vocabularies available for Enterprise clients. Startup programs offer significant credits.
For university students, Speechmatics enables accurate transcription of lectures, even with background noise or multiple speakers. This allows students to create searchable notes and review complex topics with high fidelity, improving comprehension and retention.
For small business owners, Speechmatics provides reliable transcription of client calls, including those with strong accents or technical jargon. This ensures accurate record-keeping for follow-ups and analysis, reducing the need for manual note-taking and improving client communication.
For educational content providers, Speechmatics offers real-time and batch transcription to create closed captions and searchable lesson summaries across 50+ languages. This makes educational materials accessible to a global audience and aids students with diverse learning needs.
For media production teams, Speechmatics enables scalable and cost-effective captioning and subtitling for video content, even with challenging audio. This ensures compliance with accessibility regulations and expands reach to a wider, international audience.
For medical practitioners, Speechmatics delivers precise and real-time transcription of patient interactions, supporting custom dictionaries for medical terminology. This streamlines documentation, improves accuracy in patient records, and frees up time for direct patient care.
Speechmatics offers a free tier that provides 480 minutes of Speech-to-Text and 1 million characters of Text-to-Speech per month. This tier does not require a credit card and is suitable for developers and early exploration.
Speechmatics has a tiered pricing structure. The Pro tier starts at $0.24/hr with discounts available, and Enterprise pricing is customized based on volume and specific needs. Volume discounts are automatically applied for usage above 500 hours per month.
Speechmatics is designed with enterprise-grade security, encrypting data in transit and at rest. They state compliance with GDPR, HIPAA, and SOC 2 Type II, offering a trust center with relevant documentation.
Alternatives to Speechmatics include Deepgram and AssemblyAI for developer-first voice agent builds, and Google Cloud Speech-to-Text or Amazon Transcribe if you are already within their respective ecosystems. Whisper is an open-source option for teams wanting to manage their own stack.
Speechmatics primarily offers API access for integration into applications. While they don't have a standalone mobile or desktop application, their on-device SDK support allows for offline processing in embedded scenarios.
Speechmatics can be accessed via their API, which does not require installation in the traditional sense. For on-premises or on-device deployments, you would typically deploy their provided containers or SDKs according to their documentation.
Speechmatics supports transcription in over 55 languages and dialects. They also offer AI translation for 69 language pairs and have multilingual capabilities for Arabic, Spanish, Mandarin, Malay, and Tamil.
We're still verifying the official pricing for Speechmatics. In the meantime, the most up-to-date plans and prices are available directly on the publisher's website.
