What is switch-voice?

A command that changes the active text-to-speech voice in a local voice server. TTS means turning written text into spoken audio.

Use it to switch the voice used by the local speech server and check whether that server is running.

It avoids manually editing the voice configuration file and reloads the selected voice in the running server. It accepts named voices such as LAURA, robo-LAURA, and Claude.

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	$0.00006	$0.00294
Opus 5	$0.00003	$0.00147
Sonnet 5	$0.00001	$0.00059
Haiku 4.5	$0.00001	$0.00029

Security

Grade A, and why

switch-voice scanned grade A with 1 finding 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 11d 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.

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.
