# Speech2Text Service

A D-Bus service that provides speech-to-text functionality for the GNOME Shell Speech2Text extension.

## Overview

This service handles the actual speech recognition processing using OpenAI's Whisper model locally. It runs as a D-Bus service and communicates with the GNOME Shell extension to provide seamless speech-to-text functionality.

## Features

- **Real-time speech recognition** using OpenAI Whisper
- **D-Bus integration** for seamless desktop integration
- **Audio recording** with configurable duration
- **Multiple output modes** (clipboard, text insertion, preview)
- **Error handling** and recovery
- **Session management** for multiple concurrent recordings

## Installation

### System Dependencies

This service requires several system packages to be installed (e.g. ffmpeg, clipboard tools). See the main [README.md](../README.md) for the complete list of system dependencies.

### Service Installation

The service is available on PyPI and is typically installed into a per-user virtual environment by the extension’s installer.

```bash
pip install speech2text-extension-service
```

**PyPI Package**: [speech2text-extension-service](https://pypi.org/project/speech2text-extension-service/)

Or from the source repository:

```bash
cd service/
pip install .
```

### D-Bus Registration

After installation, you need to register the D-Bus service and desktop entry. Recommended options:

1. Using the repository (local source install)

```bash
# From the repo root
./service/install-service.sh --local
```

2. Using the bundled installer (PyPI install)

```bash
# From the repo root
./service/install-service.sh --pypi
```

The installer will:

- Create a per-user virtual environment under `~/.local/share/speech2text-extension-service/venv`
- Install the `speech2text-extension-service` package
- Register the D-Bus service at `~/.local/share/dbus-1/services/org.gnome.Shell.Extensions.Speech2Text.service`
- Create a desktop entry at `~/.local/share/applications/speech2text-extension-service.desktop`

## Usage

### Starting the Service

The service is D-Bus activated and starts automatically when requested by the extension. You can also start it manually:

```bash
# If the entry point is on PATH (pip install)
speech2text-extension-service

# Or via the per-user wrapper created by the installer
~/.local/share/speech2text-extension-service/speech2text-extension-service
```

### Configuration

The service uses OpenAI's Whisper model locally for speech recognition. No API key is required. All processing happens on your local machine for complete privacy.

### D-Bus Interface

The service provides the following D-Bus interface (stable; used by the GNOME extension):

Methods:

- `StartRecording(duration, copy_to_clipboard, preview_mode)` → `recording_id`
- `StopRecording(recording_id)` → `success`
- `CancelRecording(recording_id)` → `success`
- `TypeText(text, copy_to_clipboard)` → `success`
- `GetServiceStatus()` → `status`
- `CheckDependencies()` → `all_available, missing_dependencies[]`

Signals:

- `RecordingStarted(recording_id)`
- `RecordingStopped(recording_id, reason)`
- `TranscriptionReady(recording_id, text)`
- `RecordingError(recording_id, error_message)`
- `TextTyped(text, success)`

## Requirements

- **Python**: 3.8–3.13 (Python 3.14+ not supported yet)
- **System**: Linux with D-Bus support
- **Desktop**: GNOME Shell (tested on GNOME 46+)
