Change Narrator Voice

Available Voices

Kokoro provides these voices:

Female voices:

• af_heart (default) - warm, expressive
• af_bella - clear, professional
• af_nicole - soft, gentle
• af_sarah - bright, energetic
• af_sky - calm, composed

Male voices:

• am_adam - deep, authoritative
• am_michael - warm, friendly
• am_fenrir - bold, commanding

Determine Scope

Check if the user said "locally", "for this directory", "for this project", or similar. If so, changes apply to the local config file in the current working directory.

• Global (default): ~/.claude-code-narrator/config
• Local: <cwd>/.claude-code-narrator/config

Changing the Voice

If the user specifies a voice name, read the appropriate state file and use the Edit tool to change or add the voice= line to the requested voice.

Global mode (default):

Read ~/.claude-code-narrator/config and use the Edit tool to change the voice= line.

Local mode:

Read <cwd>/.claude-code-narrator/config. If the file exists, use the Edit tool to change or add the voice= line. If the file does not exist, create the <cwd>/.claude-code-narrator/ directory if needed, then create the config file with the Write tool containing just voice=<requested_voice>.

IMPORTANT: Do NOT use sed to edit state files — use the Read and Edit tools instead.

If the user does not specify a voice, present the list above and ask which voice they would like to use.

After changing the voice, speak a test sentence to confirm:

echo "This is how I sound with the new voice." | bash "${CLAUDE_PLUGIN_ROOT}/hooks/scripts/speak.sh" --force

Changing Speed

If the user asks to change speed, read the appropriate state file and use the Edit tool to change or add the speed= line to the new value.

For local mode, if the file does not exist, create the <cwd>/.claude-code-narrator/ directory if needed, then create the config file with the Write tool containing just speed=<value>.

IMPORTANT: Do NOT use sed to edit state files — use the Read and Edit tools instead.

Valid speed range: 0.5 to 2.0. Default is 1.1.
