How to use Google Chirp 3 HD Voices in your AI Agent
Chirp 3 HD voices are Google’s most lifelike voices, designed to capture human nuance and emotion, and they sound great in multiple languages.
Step 1 – Check out the Voices!
You can hear all of the new Chirp 3 HD voices in a variety of languages including Spanish and Mandarin in the Languages section of the Syllable Console.
Log into the Syllable Console.
Click the Languages tab, then select New Language Group.
Name your new Language Group.
Add the default language. As of the time of this writing these voices support: English, Spanish, Vietnamese, Korean, and Mandarin with more on the way.
Pick Google as the voice provider.
Listen to some samples of the Chirp 3 HD voices like Aoede, Fenrir, or Kore by clicking the speaker icon.
Tweak the Voice Speed and Pitch to your liking. I recommend small increments to maintain a human timbre.
Now you can set up DTMF inputs (e.g., press 1 for English, 2 for Spanish) for the voices you've chosen for your AI Agent
Optionally, I recommend selecting "Skip reading the default language".
Click Save.
💡 Tip: If you're using the SDK, supported languages are located in the docs: list of supported languages and voice providers.
Step 2 – Connect the new Language Group to your AI Agent
Go to the Agents tab.
Select your AI Agent.
Click Edit.
In the Language Group dropdown, select the group that you just created.
Click Save.
Step 3 – Update your Agent's Opening Message
You'll want to give your customers the option to select their language of choice. This is simple on the Syllable Agentic Platform.
Open the Messages tab.
Select your Message and then click Edit.
Locate the point in your message where you’d like your agent to offer additional languages (e.g. Para Español oprima dos).
Click the Language Toggle Tool to add the voice/language menu to your message.
Click Save.
Your AI agent can switch seamlessly between languages, without repeating the full prompt in every language.
