Custom voices

Create and use a custom spoken voice when your connected provider and account support it.

Custom voices are xAI-managed voices for Cloud voice. Creation uses your own xAI key, not a shared Nock account key. xAI limits API voice creation to eligible Enterprise teams; voices created at xAI’s console can be added to Nock with Find my xAI voices. Provider eligibility and limits can change, so use the error shown by the provider if access is denied.

Check the connection

The form requires account access that includes Agent voice and your own xAI key. Open Settings → Providers to configure that key. Custom-voice creation and management use the key’s xAI team; a Nock-provided voice route is not used to create a voice. The settings page never displays a saved key. See voice settings for selecting local or cloud speech.

Create a voice

When Make a custom voice is available:

Open the voice picker under Settings → Agent → Agent voice.
Choose Make a custom voice.
Record a sample or choose a supported audio file, then play it back to check the speaker and sound quality.
Enter a name and read the consent statement. Use only your own voice or a voice you have permission to submit.
Choose Create voice only after reviewing what will be sent to the voice provider.

The form currently accepts clips up to two minutes and audio files up to 50 MB. It can record a sample or choose WAV, MP3, M4A, FLAC, OGG, Opus, AAC, or MP4 audio. The current interface offers Find my xAI voices for custom voices made through xAI’s console; API creation through the form requires xAI Enterprise access. Do not submit a full conversation or a clip that includes private material you did not intend to share. Choosing a file sends a copy to xAI for voice processing; it does not move the original file.

Use, refresh, or remove a voice

Created voices appear in the cloud voice picker when the connected provider account makes them available. Find my voices may refresh the provider’s list. If you change accounts, a saved voice may no longer be accessible.

Read the confirmation before deleting. Depending on the provider, deletion can remove the voice from that provider account, not merely hide it in Nock. If the voice becomes unavailable, select a built-in cloud voice and play its preview.

If creation or playback fails

An account-eligibility message must be resolved with the provider; repeated submissions do not change eligibility. Re-record if the draft expired or the clip is unclear. For microphone issues, see voice troubleshooting. Provider permissions and limits can change, so follow the message shown by the form rather than relying on a particular price or account tier.
