Gladia

For audio production professionals, accuracy is non-negotiable. Gladia delivers with its Solaria-3 model, achieving a 9.6% Word Error Rate (WER) on real English audio and claiming a 29% higher accuracy rate than alternatives on conversational speech. This isn't just about clean transcripts; it's about reliability for downstream tasks like subtitling, editing, and feeding language models. The API processes audio with less than 300ms latency for real-time applications and supports over 100 languages, including seamless code-switching for multilingual content. Crucially, features that often cost extra with other services—like top-tier speaker diarization (3x lower error rate than competitors), sentiment analysis, and PII redaction—are built-in. This consolidation simplifies the tech stack and budget. With a 99.95% uptime SLA, SOC 2 Type II compliance, and default opt-out for data training, Gladia is built for professional, scalable workflows where data integrity and performance are paramount.
