Tool Information
Gladia provides speech-to-text and audio intelligence APIs for live and prerecorded transcription, diarization, translation, summaries, and other voice workflows. Developers should obtain recording consent, protect audio and transcripts, verify speakers and specialist terminology, secure API keys, test latency and languages, and monitor usage.
Begin with authorized, non-sensitive inputs and a limited test. Configure privacy, access, quality, export, disclosure, evaluation, consent, moderation, security, and spending controls; compare results with authoritative sources and real requirements; correct errors; and keep a responsible person in control before publication, deployment, outreach, purchases, automation, or consequential changes.
Free credits or limited testing are available with usage-based paid pricing. Audio duration, live or batch mode, models, add-ons, volume, and enterprise terms affect cost.
AI output may be inaccurate, generic, biased, incomplete, stale, unsafe, insecure, or misleading. Review privacy, retention, training, copyright, consent, dependencies, secrets, security, renewals, refunds, and commercial rights, and require qualified human review before merging code, publishing, spending, or consequential changes.
