Gladia
Customers send voice messages, leave voicemails, or reference recorded calls. Your AI agent sends the audio to Gladia for transcription, retrieves the text in 100+ languages, and responds based on what was said. Support interactions that once required manual listening now resolve automatically.




From uploading recordings to initiating live transcription sessions, your AI agent processes audio through Gladia's speech-to-text engine and delivers text results in under 300 milliseconds.

Discover how businesses transform voice messages, call recordings, and meeting audio into actionable text that their AI agents can understand and act on.
A customer sends a WhatsApp voice note describing a product defect. Your AI Agent uploads the audio to Gladia, initiates pre-recorded transcription with speaker diarization, retrieves the full text transcript, and identifies the issue described. The agent then responds with troubleshooting steps based on the transcribed complaint. No support agent ever listens to the recording.
After a client onboarding call, the account manager uploads the recording. Your AI Agent sends it to Gladia with summarization enabled, waits for the job to complete, and retrieves both the full transcript and an AI-generated summary with key action items. The team gets meeting notes delivered in chat within minutes of the call ending.
A global support center receives calls in Spanish, French, and English. Your AI Agent initiates Gladia live sessions with automatic language detection enabled. The transcription engine identifies the language on the fly, transcribes accurately across all three, and the agent responds in the customer's language. No manual language routing needed.

FAQs
Gladia delivers live transcription at sub-300 millisecond latency. The agent initiates a WebSocket-based live session, and as audio streams in, text results arrive almost instantly. This is fast enough for real-time conversation analysis, live captioning, and immediate agent responses.
Gladia accepts most common audio and video formats including MP3, WAV, MP4, FLAC, OGG, and WebM. You can provide a public URL to the file or upload it directly through the API. The agent handles format detection automatically when submitting files for transcription.
Yes. Gladia supports transcription in over 100 languages with automatic language detection. The agent can also enable code-switching, which handles conversations where speakers switch between languages mid-sentence. Language configuration is passed as a parameter when initiating transcription.
No. Audio files are uploaded directly to Gladia's servers for processing. Transcription results are fetched via the API and used only to formulate the agent's response. Tars does not maintain copies of your audio content or transcripts on its own infrastructure.
Yes. Speaker diarization is available as a configuration option when initiating pre-recorded transcription. The agent passes the diarization_config parameter, and Gladia labels each segment of the transcript with the identified speaker, making it clear who said what during multi-person recordings.
A standalone service gives you a transcript. Tars gives you an AI agent that reads the transcript, understands the customer's intent, and takes action. If a voice message contains a complaint, the agent does not just transcribe it but also identifies the issue and starts resolving it automatically.
Gladia uses its Solaria-1 model by default, built on an enhanced and optimized version of OpenAI Whisper called Whisper-Zero. This model eliminates up to 99% of hallucinations from transcripts while maintaining high accuracy across languages and accents. The model parameter can be configured per request.
Yes. When initiating pre-recorded transcription, the agent can enable the subtitles_config parameter. Gladia generates properly timed subtitle output alongside the transcript, suitable for embedding in video content or displaying as captions. SRT and VTT formats are supported.
