A guide for changing the voice used by a text-to-speech narrator, including the available female and male voices. It explains whether the change applies everywhere or only to the current project.

Use it to select, list, or switch the narrator voice globally or for one directory or project.

It removes the need to edit the narrator's configuration by hand and helps ensure the voice is changed in the intended scope.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.00623
Opus 5	$0.00026	$0.00311
Sonnet 5	$0.00011	$0.00125
Haiku 4.5	$0.00005	$0.00062

Measured 10d ago against content hash 7ebffb889115, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-10, from the pricing page.

Security

Grade A, and why

cast scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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>.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
