What it does
Speech Use is an agent skill from cnemri/google-genai-skills. Generate (TTS), Transcribe (STT), and Clone voices using Google's GenAI and Cloud Speech SDKs. Supports Gemini-TTS, Chirp 3, and Instant Custom Voice.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/voices.md`, `scripts/create_custom_voice.py` and `scripts/generate_speech.py`).
It sits in Media & Creative, covering Text to speech and voice and Transcription. The licence is MIT.
When your agent uses it
- Tasks that involve Text to speech and voice
- Tasks that involve Transcription
Example prompts
- “/speech-use”
Requirements
- Python 3
- A credential in GOOGLE_API_KEY
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 7277476. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GOOGLE_API_KEYGOOGLE_APPLICATION_CREDENTIALS
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Speech Use loads about 616 tokens when it runs, and up to ~937 if it reads all its reference files. Until then it costs about 40 tokens; SKILL.md has 195 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- speech-use
- description
- Generate (TTS), Transcribe (STT), and Clone voices using Google's GenAI and Cloud Speech SDKs. Supports Gemini-TTS, Chirp 3, and Instant Custom Voice.
Speech Use
Use this skill to perform Text-to-Speech (TTS), Speech-to-Text (STT), and Voice Cloning operations.
This skill uses portable Python scripts managed by uv.
Prerequisites
Environment Variables:
GOOGLE_API_KEY(for TTS via Gemini)GOOGLE_CLOUD_PROJECT(Required for STT and Voice Cloning)GOOGLE_APPLICATION_CREDENTIALS(Recommended for STT/Voice Cloning)
APIs Enabled:
- Text-to-Speech API (
texttospeech.googleapis.com) - Speech-to-Text API (
speech.googleapis.com)
- Text-to-Speech API (
Usage
1. Generate Speech (TTS)
Generate audio from text using Gemini-TTS.
Standard Voice:
uv run skills/speech-use/scripts/generate_speech.py "Hello world, this is a test." --voice Puck --output hello.wavCustom Voice (Cloned):
uv run skills/speech-use/scripts/generate_speech.py "This is my custom voice speaking." --voice-cloning-key "YOUR_KEY_HERE" --output custom.wav2. Create Custom Voice (Voice Cloning)
Generate a voiceCloningKey from a reference audio file and a consent file.
Requirements:
reference.wav: 10-30s of clear speech (the voice to clone).consent.wav: The speaker saying: "I am the owner of this voice and I consent to Google using this voice to create a synthetic voice model."
uv run skills/speech-use/scripts/create_custom_voice.py --reference-audio reference.wav --consent-audio consent.wavSave the output key to use with generate_speech.py.
3. Transcribe Audio (STT)
Transcribe audio files using Chirp 3.
uv run skills/speech-use/scripts/transcribe_audio.py audio.wav --language en-US --output transcript.txtOptions
generate_speech.py
--voice: Prebuilt voice (e.g.,Kore,Puck,Fenrir,Aoede).--voice-cloning-key: Key fromcreate_custom_voice.py.--model: Defaultgemini-2.5-flash-preview-tts.
transcribe_audio.py
--model: Defaultchirp_3.--language: Defaultauto.--location: Cloud region (defaultus).

Can I use Speech Use in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cnemri/google-genai-skills --skill speech-use -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/speech-use, .gemini/skills/speech-use, .github/skills/speech-use and .opencode/skills/speech-use in your project.
What does Speech Use need to run?
Going by SKILL.md and its folder, Speech Use needs Python for the scripts in its folder, the command-line tools its instructions call (uv) and credentials named GOOGLE_API_KEY and GOOGLE_APPLICATION_CREDENTIALS. Our summary lists: Python 3; A credential in GOOGLE_API_KEY.
Does Speech Use access the network?
SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Speech Use safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
