Speechmatics
Speechmatics sells speech APIs for turning live and recorded audio into text across 56+ languages, with translation pairs and a growing text-to-speech stack for voice agents. Developers call real-time and batch endpoints, pick between Enhanced, Standard, or the multilingual Melia model, and deploy in cloud or on-premises environments depending on privacy needs.
Whisper-style open models are cheap to self-host but leave you tuning accuracy, diarization, and language coverage yourself. Speechmatics bundles proprietary models trained on decades of Cambridge speech research, volume discounts past 500 hours per month, and SOC 2, ISO 27001, GDPR, and HIPAA certifications out of the box. The Melia model handles speakers who switch languages mid-sentence without picking a locale upfront.
Voice AI startups, contact centers, media monitoring teams, and healthcare transcription vendors integrate the API when latency and language breadth matter more than rolling their own stack. New accounts get $100 in credit with no card required, Pro usage bills from $0.129 per hour, and enterprise deals add custom models plus private deployment.
