Native French Text to Speech

The recorded examples on this page use Étienne, Josette, Henri, and Inès. Select an example to hear its script, then replace the text to test that voice with your own words. You can explore more voices in Cartesia Playground.

French text to speech converts a written script into spoken audio. You can use it for narration, accessibility, product interfaces, and the spoken responses of a voice agent. Speech generation does not translate the script or decide what an agent should say.

Compare pronunciation, response time, streaming support, and output formats using the same scripts and playback setup. Include interruptions, short replies, and longer passages from your actual workflow. Have fluent French speakers review the voices before choosing one.

Combine speech recognition, conversation logic, and text to speech, or use Managed Agents to bring those parts together. Choose a voice, connect the tools your workflow needs, and test real conversations with fluent speakers. Define when the agent should ask for clarification or hand the conversation to a person.

Time to first audio depends on the model, request, network connection, and client playback. A voice agent also includes speech recognition and response-generation time. Measure the complete conversation in your deployment; measure time to first audio separately from the time a caller waits for an answer.

Test the formats your users will hear, including local dates, prices, phone numbers, and addresses. Write ambiguous values in the form you want spoken and review the generated audio. Names, abbreviations, and regional conventions deserve a separate pronunciation check.

Send your script, model, language code, voice ID, and output settings to the speech API from your server. Keep API credentials on your server. Start with the text-to-speech API, then add playback, cancellation, and error handling in your application.

Sonic offers output settings for browser players and telephony. Choose a container, encoding, and sample rate that your player accepts. The text-to-speech API reference lists the supported combinations. Match these settings to your phone provider when generating call audio.

You can connect generated speech to a telephony application. Configure the output to match your provider's audio requirements and test it over real calls. Your application still controls call routing, caller verification, interruptions, and transfers to a person.

Test French pronunciation, concurrent traffic, failure handling, and your target response times. Review data handling, deployment options, and contractual requirements with your team and Cartesia. Validate the complete integration before expanding from a pilot to production.

Yes. Use Sonic to read French scripts for product tutorials, spoken articles, and other narration. Preview a short passage first to check pacing and pronunciation. For longer recordings, continue in Cartesia Playground or generate audio through the API.

Play a recorded example on this page, or edit the script to generate new French speech with Sonic. The web demo accepts up to 500 characters. For longer scripts and downloads, open Cartesia Playground.

This page includes examples labelled Canadian French and French. Listen to the individual recordings to choose a voice for your audience. The labels describe these recordings, not a guarantee that every regional accent is available.

Yes. Select a voice and replace the sample script with your own text. The demo generates new audio for edited scripts. Changing to another example replaces your edits with that example's script.

Yes. Sonic supports streaming speech generation. Set the language code and voice ID in your request. Streaming lets your application begin playback as audio arrives. Check the API reference for request and output settings.

Cartesia offers voice cloning. Use a recording you have permission to clone, then test pronunciation and speaker similarity in French before using the voice in production. Results depend on the recording and selected model.

No. Sonic generates speech from the text you supply. If your source material is in another language, translate and review it in French first. For a multilingual project, see our localization workflow.
