Gladia review

Gladia sells one speech-to-text layer with transcription and audio intelligence bundled into the same request. Its Solaria models cover 100+ languages in both batch and real-time modes and handle sentences that switch language mid-flow without breaking timestamps. Diarization, sentiment analysis, named entity recognition and custom vocabulary are part of the core API, and add-ons such as translation and PII redaction are billed per hour only when you turn them on. Gladia states GDPR, HIPAA, SOC 2 Type II and ISO 27001 compliance and offers EU data residency, which matters for European call recording. Self-serve plans include 30 concurrent requests, rates drop automatically as monthly volume grows, and large top-ups earn bonus credits. Pricing from our location was shown only in euros, so we could not confirm a USD rate; check the vendor's page from a US account before you budget.
