Why people use Cartesia (Voice AI)

Cartesia Voice AI for Low-Latency Speech Synthesis

This Connector changes that by giving your agent direct access to Sonic models. You get high-fidelity audio that responds in real time. It makes your bot feel like a human on the other end of the line instead of a machine reading a script.

What Vinkius changes

You get human-sounding speech and transcription without building your own audio engine.

Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect

Questions about Cartesia.

The practical details behind the request, access and result.

Does Cartesia Voice AI support real-time conversation?

Yes, it supports real-time speech. By using the streaming capabilities, your AI agent can respond with almost zero delay, making it perfect for voice bots.

How do I make the AI say technical words correctly?

You can create a custom dictionary of words. This tells the AI exactly how to pronounce specific terms, brand names, or industry jargon.

Can I use my own voice for an AI agent?

Yes, you can clone a voice from a short audio clip. This allows you to create a custom voice model that sounds just like you or anyone else.

Is there a way to transcribe multiple files at once?

Yes, the Connector includes a batch transcription capability. You can send a whole list of audio files and get the text back in one go.

How do I see if I'm running out of credits?

You can ask your agent to check your usage stats. It will pull your current credit balance and tell you how much you have left for the month.

Can the AI speak in different accents?

Yes, the Connector allows you to adapt a voice to a new language or dialect. This is great for making your content feel local to different countries.

Can I generate audio in different formats like MP3 or WAV?

Yes. Using the tts_bytes capability, you can specify the output_format_container as 'mp3', 'wav', or 'raw', and configure the sample rate and encoding to match your needs.

How do I transcribe an existing audio file to text?

Use the stt_batch capability. Provide the base64 encoded audio file, specify the model (e.g., 'ink-whisper'), and the language code to receive a full transcription.

Is it possible to clone a voice using this integration?

Absolutely. The clone_voice capability allows you to create a new voice model by uploading a short (approx. 5s) base64 encoded audio clip.
