Talkdesk Autopilot’s Voice settings page allows you to configure the Autopilot's synthesized voice, including language detection, voice profiles, and advanced behavioral traits.
It is possible to select up to 5 languages/voices for each Autopilot that uses voice.
Note: Autopilot Agentic using digital channels (chat, SMS, etc.) has no limitation in terms of languages, as generative AI models speak the majority of the world's spoken languages.
To configure your Autopilot's voice settings, follow these steps:
1. Open the Autopilot app, select the Autopilot that you’ll be modifying, and choose the Channels tab [1].
2. Then, select the Voice channel [2] to access all settings.
1. Configure General Voice Settings
[Preview] Capture keypad input (DTMF)
2. Adjust End of Speech Sensitivity
3. Select Your Primary Voice Setting
For Neural and Neural HD Voices
5. Add Secondary Languages (Language Sets)
6. Testing your Voices and Languages
At the top of the Voice settings page, you can enable core interaction behaviors:
If enabled, users can bypass the Autopilot response without having to wait for the entire sentence to finish. The autopilot will detect prompts in real-time and reply accordingly.
When enabled, this setting adds a short period of time at the start of a call during which the contact cannot interrupt the autopilot. After the delay, barge-in is enabled as normal. This setting is disabled by default, and the maximum allowed is 20 seconds, long enough to accommodate extended welcome messages, including those with legal disclosures.
Notes:
Note: This is a preview feature, available on request for select customers.
Enable this so the autopilot can extract and use numbers sent by the contact person via their phone's keypad.
DTMF (Dual-Tone Multi-Frequency) is ideal for noisy environments or when the contact needs to share sensitive information that cannot be said aloud (e.g., PIN codes, account numbers, date of birth).
The setup is automatic, but we recommend instructing the contact to use the keypad and press the pound key (#) to submit all entered digits.
Example phrasing the AI Agent can use:
\"You can use your keypad and press the pound key # to finalize the inclusion.\"
When Capture keypad input (DTMF) is enabled, the Autopilot accepts keypad input from the contact on the next call onwards.
How DTMF input is captured
Pressing # at any time immediately submits all digits entered so far as the contact's response.
\n\n
This allows the Autopilot to automatically detect the language of incoming messages.
Notes:
Use the slider to determine how much time the autopilot waits for the contact to finish answering.
This is the default voice and language your Autopilot will use.
Available languages vary and will keep expanding with more languages and voices available. See more here for the current list of AI Supported Languages.
When selecting a voice profile, you will see three distinct types of voices.
Note: If you plan to add secondary languages later, the voice type you select here dictates what you can select later. Natural voices can only be paired with other Natural voices, while Neural/Neural HD voices must be paired with other Neural/Neural HD voices.
Depending on the type of Voice Profile you selected in Step 3, clicking Advanced configuration will reveal different tuning options:
To make your Autopilot multilingual, click Add more languages at the bottom of the page. You can add up to 4 additional languages (for a total limit of 5 languages per Autopilot).
When finished making the adjustments, click Save [8].
If you wish to listen to the new Autopilot’s voice profile, go to the Phone or Conversations app and perform an outgoing call to a number associated with your Autopilot to know how the new settings sound to your callers.
Alternatively, you can visit the AI Agents Platform, choose the agent that is connected to your specific Autopilot, and then click “Test”.
