In their own words
Gladia
Gladia provides audio infrastructure through an API for recording, transcribing, and enriching audio. It offers asynchronous and real-time transcription, including live streaming, with Starter supporting 100+ languages and automatic language detection and switching. Listed audio tools include speaker diarization, sentiment analysis, PII redaction, entity detection, and audio-to-LLM processing. Developers can use Python or Node.js SDKs, WebSocket streaming, or REST uploads; named integrations include Pipecat, LiveKit, Twilio, Retell, Zapier, Make, and n8n. Transcripts can include speaker labels and timestamps, and SRT and VTT are listed export formats. Starter is listed at free and includes 50€ in one-time credits that do not expire. Flexible pay-as-you-go Starter rates are $0.61 a month for asynchronous transcription and $0.75 a month for real-time transcription. Hourly call and total audio limits vary by tier. Gladia also offers GladiaFlow, a desktop voice dictation app for Mac and Windows; its code is available under the MIT license.
