# MMM-WebSpeechTTS

A Text-To-Speech service module for [MagicMirror²](https://github.com/MagicMirrorOrg/MagicMirror) that wraps the browser Web Speech API and exposes a reusable queue with translation-aware producers.

## Project status

The module focuses on providing a speech service and is ready for day-to-day tinkering. Expect APIs and defaults to evolve; feedback and contributions are very welcome!

## Features

- 🔊 Central speech queue driven by the browser’s Web Speech API (no server required).
- 🌐 Automatic language detection with optional overrides for language, voice, rate, pitch, and volume.
- 💬 Notification-based API (`WEB_SPEECH_TTS_*`) for other modules to enqueue or stop speech.
- 🖥️ Lightweight browser helper (`window.mmmWebSpeechTts`) for custom scripts, debug consoles, and bookmarklets.
- 🤝 Built-in producers:
  - Startup greeting (greeting + current time).
  - Keyboard shortcuts (`g`, `s`, `t`) for greeting, stop, and time.
  - MMM-PublicTransportHafas integration for departure announcements.
- 🔁 Simple FIFO speech queue—every request lines up automatically.
- 🌍 English and German localizations with automatic fallback.

  WebSpeech["Browser/Electron<br>Web Speech API"]
  SpeechDispatcher["speech-dispatcher<br>(optional Linux backend)"]

When MagicMirror² is started with `--enable-speech-dispatcher` (recommended on Linux), Electron's Web Speech API will route synthesis requests to the system-level `speech-dispatcher` daemon, unlocking voices provided by TTS engines.

If you are running MagicMirror² in a browser (e.g., Firefox or Chrome), the module will use the built-in voices available in that browser. In this case, `speech-dispatcher` is not required and browser-based cloud TTS may provide better quality.

## Installation

1. Clone this module into your MagicMirror² modules directory.

```bash
   cd ~/MagicMirror/modules
   git clone https://github.com/KristjanESPERANTO/MMM-WebSpeechTTS
   ```

2. **Install TTS engine (Linux with Electron)**

### Option A: Piper (Recommended - Neural TTS)

Piper provides high-quality neural text-to-speech that sounds significantly better than traditional engines like espeak-ng.

**Install Piper:**

```bash
   pip3 install piper-tts
   ```

**Download voice models:**

```bash
   # Create voices directory
   mkdir -p ~/.local/share/piper/voices
   cd ~/.local/share/piper/voices

# English (US) - Lessac voice
   wget https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/en/en_US/lessac/medium/en_US-lessac-medium.onnx
   wget https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/en/en_US/lessac/medium/en_US-lessac-medium.onnx.json

# German - Thorsten voice (optional)
   wget https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/de/de_DE/thorsten/medium/de_DE-thorsten-medium.onnx
   wget https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/de/de_DE/thorsten/medium/de_DE-thorsten-medium.onnx.json
   ```

> **More voices:** Browse all available voices at <https://huggingface.co/rhasspy/piper-voices/tree/v1.0.0>
   >
   > Download pattern: `https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/{language}/{locale}/{voice}/{quality}/{model_name}.onnx`

**Configure speech-dispatcher to use Piper:**

```bash
   # Install speech-dispatcher if not already installed
   sudo apt-get install speech-dispatcher

# Create user config directory
   mkdir -p ~/.config/speech-dispatcher/modules

# Create Piper module configuration
   cat > ~/.config/speech-dispatcher/modules/piper.conf << 'EOF'
   # Piper TTS output module for Speech Dispatcher

# Choose one GenericExecuteSynth line (English or German):
   # English voice
   GenericExecuteSynth "echo '$DATA' | piper --model ~/.local/share/piper/voices/en_US-lessac-medium.onnx --output-raw | aplay -q -r 22050 -f S16_LE -t raw -"

# German voice (uncomment to use)
   #GenericExecuteSynth "echo '$DATA' | piper --model ~/.local/share/piper/voices/de_DE-thorsten-medium.onnx --output-raw | aplay -q -r 22050 -f S16_LE -t raw -"

AddVoice "en" "MALE1" "en_US-lessac-medium"
   AddVoice "de" "MALE1" "de_DE-thorsten-medium"
   DefaultVoice "en_US-lessac-medium"

GenericRateAdd 50
   GenericPitchAdd 50
   GenericVolumeAdd 50
   Debug 0
   EOF

# Configure speech-dispatcher to use Piper
   cat > ~/.config/speech-dispatcher/speechd.conf << 'EOF'
   # Speech Dispatcher configuration for Piper TTS
   DefaultModule piper
   AddModule "piper" "sd_generic" "piper.conf"
   AudioOutputMethod "alsa"
   EOF
   ```

**Test Piper:**

```bash
   # Test directly
   echo "Hello, this is Piper speaking!" | piper --model ~/.local/share/piper/voices/en_US-lessac-medium.onnx --output-raw | aplay -r 22050 -f S16_LE -t raw -

# Test via speech-dispatcher
   spd-say "Hello from Piper through speech dispatcher!"
   ```

### Option B: espeak-ng (Fallback - Traditional TTS)

If you prefer a simpler setup or Piper doesn't work for your system, you can use espeak-ng. Note that espeak-ng uses formant synthesis and sounds more robotic than neural TTS engines like Piper.

```bash
   sudo apt-get install espeak-ng speech-dispatcher
   ```

## Configuration

Add the module to your `config.js` and customize the service and producers as needed:

```js
    {
      module: "MMM-WebSpeechTTS",
      position: "top_left",
      config: {
        hidden: true,
        speechLang: "en-US",
        speechVoice: "",
        speechRate: 1,
        speechPitch: 1,
        speechVolume: 1,
        translationLang: "",
        producers: {
          greeting: {
            enabled: true,
            delay: 8000
          },
          keyboard: {
            enabled: true,
            shortcuts: {
              greeting: "g",
              stop: "s",
              time: "t"
            }
          },
          publicTransport: {
            enabled: true,
            shortcut: "d"
          }
        }
      }
    },
```

### Core options

| Option            | Default              | Description                                                                                 |
| ----------------- | -------------------- | ------------------------------------------------------------------------------------------- |
| `hidden`          | `true`               | Hide the text wrapper (set to `false` to display current speech text).                      |
| `text`            | `"MMM-WebSpeechTTS"` | Placeholder text shown when idle and `hidden:false`.                                        |
| `speechLang`      | `""`                 | BCP-47 language tag. If empty, resolves from `config.locale`/`config.language`.             |
| `speechVoice`     | `""`                 | Preferred voice name. Leave empty to auto-select the first matching voice for `speechLang`. |
| `speechRate`      | `1`                  | Playback rate (0.1 – 10). Overrides available per job.                                      |
| `speechPitch`     | `1`                  | Pitch (0 – 2). Overrides available per job.                                                 |

| `translationLang` | `""`                 | Force translation language; otherwise derived from `speechLang` or MagicMirror locale.      |
| `service`         | `{}`                 | Optional overrides mirroring the core options above (useful when sharing config snippets).  |

### Producer options

| Producer          | Key                         | Description                                                                              |
| ----------------- | --------------------------- | ---------------------------------------------------------------------------------------- |
| `greeting`        | `producers.greeting`        | `enabled`, optional `delay` (ms) before speaking.                                        |
| `keyboard`        | `producers.keyboard`        | `enabled`, custom `shortcuts` for `greeting`, `stop`, `time`. Keys are case-insensitive. |
| `publicTransport` | `producers.publicTransport` | `enabled`, keyboard `shortcut`. Requires MMM-PublicTransportHafas in your mirror.        |

## Notification API

Send notifications from any module to control the speech queue:

| Notification                 | Direction | Payload                                                                               |
| ---------------------------- | --------- | ------------------------------------------------------------------------------------- |
| `WEB_SPEECH_TTS_SAY`         | inbound   | `{ text: "Hello", id?, lang?, voice?, rate?, pitch?, volume? }`                       |
| `WEB_SPEECH_TTS_STOP`        | inbound   | `{ id? }` — stop a specific job or everything when `id` is omitted.                   |
| `WEB_SPEECH_TTS_GET_VOICES`  | inbound   | `{ requestId? }` — request available voices (async).                                  |
| `WEB_SPEECH_TTS_VOICES_LIST` | outbound  | `{ voices: VoiceInfo[], requestId }` — list of `{name, lang, localService, default}`. |
| `WEB_SPEECH_TTS_STARTED`     | outbound  | `{ id, text }` — emitted when a job starts speaking.                                  |
| `WEB_SPEECH_TTS_ENDED`       | outbound  | `{ id, text, reason, error }` — emitted when a job finishes or is cancelled.          |

> **Legacy:** The old `WebSpeechTTS` notification still works but logs a warning. Please migrate to `WEB_SPEECH_TTS_SAY`.

### Using the browser helper

The module exposes a small helper on the MagicMirror browser window:

```js
// enqueue speech
window.mmmWebSpeechTts.say({
  text: "The kettle is ready."
});

// stop everything
window.mmmWebSpeechTts.stop();

// fetch voices (optional requestId to match responses)
window.mmmWebSpeechTts.getVoices("debug-panel");
```

This is handy when debugging in the dev tools console or when creating custom producers outside the module.

## Keyboard control

Default shortcuts reflect the sample configuration above:

| Key | Action                                | How to customize                               |
| --- | ------------------------------------- | ---------------------------------------------- |
| `g` | Speak greeting                        | `config.producers.keyboard.shortcuts.greeting` |
| `s` | Stop speech                           | `config.producers.keyboard.shortcuts.stop`     |
| `t` | Speak current time                    | `config.producers.keyboard.shortcuts.time`     |
| `d` | Departures (MMM-PublicTransportHafas) | `config.producers.publicTransport.shortcut`    |

Disable the keyboard producer entirely via `config.producers.keyboard.enabled = false` if you rely on external input (e.g., MQTT, sensors).

## Run it

MagicMirror² must be launched with speech synthesis enabled:

1. **Adapt `package.json`** of MagicMirror²
   - Add: `"start:tts": "speech-dispatcher -s -t 0 & node --run start:wayland -- --enable-speech-dispatcher"`
   - Start with `node --run start:tts`
2. **Direct command**
   - Run: `speech-dispatcher -s -t 0 & node --run start:wayland -- --enable-speech-dispatcher`
3. **Server mode**
   - Run `node --run server` and open MagicMirror² in a browser supporting the Web Speech API (Firefox works best on Linux).

## Update

```bash
cd ~/MagicMirror/modules/MMM-WebSpeechTTS
git pull
```

## ToDo/Ideas

- Add producer for all core MM modules (e.g., weather, news, calendar).
- Add producer to announce when a new module is loaded.
- Add practical examples for custom producers.
- Add practical examples for use cases.
  - Announcing important events (e.g., reminders, alarms).
  - Providing real-time updates (e.g., weather, news).
  - Announcing notifications (e.g., emails, messages).
  - Read news headlines aloud on GPIO button press.
  - ... your idea here!
- Mention in MMM-Public-TransportHafas that TTS is possible with this module
- Expand translations beyond English and German.
- Document additional producer examples (sensors, calendar, reminders).
