Persona Voice is a desktop app that replaces the spoken output of ChatGPT, Codex or Grok Bot with a voice you choose, converting it locally in near real time with Chatterbox or Seed-VC models.

This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL.

## How to give your AI assistant a different voice with Persona Voice

Repo: [miuuyy/persona-voice](https://github.com/miuuyy/persona-voice) | Difficulty: Intermediate | Time: 30 minutes | Basis: From the README

Run Persona Voice so the spoken replies from ChatGPT, Codex or Grok Bot are converted on your machine, in near real time, into a voice you choose.

**Who it is for:** Someone who talks to ChatGPT or Codex by voice every day and wants a different voice, such as a credited VOICEVOX character or their own authorised reference.

**The problem:** Built-in assistant voices are fixed, and voice changers that run in the cloud send your audio to someone else's servers.

**The outcome:** Assistant replies played through a local voice model with your chosen reference, with settings, models and history kept on your machine.

### Steps

1. Download a preview package for Apple Silicon macOS, Linux with NVIDIA or Windows with NVIDIA, or run from source
2. From source: `git clone --recurse-submodules https://github.com/miuuyy/ChatGPT-Persona-Voice.git` and `cd ChatGPT-Persona-Voice`
3. Install and start: `bun install --frozen-lockfile` then `bun run dev`
4. Download one voice model during first-run setup
5. Pick the source app and a bundled identity, or add an authorised private reference
6. Speak to your assistant and listen through the converted route

```text
Help me set up miuuyy/persona-voice from source on this <macOS or Linux or Windows> machine: check the platform requirements from the README, run bun install --frozen-lockfile and bun run dev, and walk me through first-run model setup.
```

### Caveat

Windows needs CUDA 13.0 and a separately installed VB-CABLE; Linux needs CUDA 13.0, PipeWire and WirePlumber.

Risk, voice cloning: Use only reference voices you own or are authorised to use, and never present converted speech as a real person's.

## How to choose the right voice model for your language with Persona Voice

Repo: [miuuyy/persona-voice](https://github.com/miuuyy/persona-voice) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README

Pick Chatterbox for English and most languages, or Seed-VC Tiny for Japanese and Chinese, and switch later in Settings without reinstalling.

**Who it is for:** A Persona Voice user who speaks to their assistant in Japanese, Chinese or English and wants the best quality and latency.

**The problem:** One voice model does not fit every language, and picking wrong gives worse accent, quality or delay.

**The outcome:** The model that fits your language and hardware, with streaming block size and speed you understand before you commit.

### Steps

1. Install Persona Voice and start first-run setup
2. For English and most other languages, download Chatterbox (640 ms streaming blocks on Apple Silicon)
3. For Japanese or Chinese, download Seed-VC Tiny (300 ms streaming blocks)
4. Add the other model later in Settings, Voice model
5. Compare both on the same recording; on an M4 Pro Chatterbox used 29% less processing time in English
6. Check docs/VOICE_MODELS.md for startup delay and storage before downloading both

### Prompt to paste into your agent

```text
I use Persona Voice mostly in <language> on <hardware>. Based on the README's voice model table, which model should I download first, what latency should I expect, and how do I switch later?
```

### Caveat

Quality varies by language and voice.

## How to build and smoke test Persona Voice from source with Persona Voice

Repo: [miuuyy/persona-voice](https://github.com/miuuyy/persona-voice) | Difficulty: Intermediate | Time: 30 minutes | Basis: From the README

Clone Persona Voice with its submodules and run its tests, type checks and engine smoke test before you trust a build or send a change.

**Who it is for:** A contributor or careful user who wants to verify the desktop app before running it with their microphone and system audio.

**The problem:** Audio routing apps touch sensitive audio, and a broken engine or missing submodule fails in confusing ways at runtime.

**The outcome:** A source build that passes unit tests, type checks, the full check and an engine smoke test.

### Steps

1. Clone with submodules: `git clone --recurse-submodules https://github.com/miuuyy/ChatGPT-Persona-Voice.git`
2. Install: `bun install --frozen-lockfile`
3. Run tests with `bun run test` and types with `bun run typecheck`
4. Build the interface with `bun run build:renderer`
5. Run the engine smoke test: `bun run smoke:engine`
6. Run `bun run check` before opening a pull request

### Prompt to paste into your agent

```text
Clone miuuyy/ChatGPT-Persona-Voice with submodules, run bun run test, bun run typecheck, bun run smoke:engine and bun run check, and summarise any failures with the file and likely cause.
```

### Caveat

The clone URL is ChatGPT-Persona-Voice, different from the listed repo name.
