## Description
**Speech Note** let you take, read and translate notes in multiple languages.
It uses Speech to Text, Text to Speech and Machine Translation to do so.
Text and voice processing take place entirely offline, locally on your
computer, without using a network connection. Your privacy is always
respected. No data is sent to the Internet.
**Speech Note** uses many different processing engines to do its job.
Currently these are used:
- Speech to Text (STT)
- [Coqui STT (a fork of Mozilla DeepSpeech)](https://github.com/coqui-ai/STT)
- [Vosk](https://alphacephei.com/vosk)
- [whisper.cpp + Parakeet](https://github.com/ggerganov/whisper.cpp)
- [Faster Whisper](https://github.com/guillaumekln/faster-whisper)

- [dsnote-git](https://aur.archlinux.org/packages/dsnote-git)
- openSUSE ([Packman repository](https://en.opensuse.org/Additional_package_repositories#Packman))
```sh
# Base package
zypper in speechnote
# Optional support for Python-based features in Speech Note
zypper in speechnote-python-modules
```
- Sailfish OS: [OpenRepos](https://openrepos.net/content/mkiol/speech-note)
### Flatpak packages
The app distributed via Flatpak (published on Flathub) consists of the following packages:
- Base package "Speech Note" (net.mkiol.SpeechNote)
- Optional add-on for NVIDIA graphics card "Speech Note NVIDIA" (net.mkiol.SpeechNote.Addon.nvidia)
- Optional add-on for AMD graphics card "Speech Note AMD" (net.mkiol.SpeechNote.Addon.amd)
Base package includes all the dependencies needed to run every feature of the application.
Add-ons add the capability of GPU acceleration, which speeds up some operations in the application.
Base package and add-ons contain many "heavy" libraries like CUDA, ROCm, Torch and Python libraries.
Due to this, the size of the packages and the space required after installation are significant.
If you don't need all the functionalities, you can use much smaller "Tiny" package
(available on [Releases](https://github.com/mkiol/dsnote/releases) page),
which provides only the basic features. If you need, you can also use "Tiny" packages together with GPU acceleration add-on.
Size comparison between Base, Tiny and Add-ons Flatpak packages:
| **Sizes** | **Base** | **Tiny** | **AMD add-on** | **NVIDIA add-on** |
| ------------- | ---------| ---------| -------------- | ----------------- |
| Download size | 1.2 GiB | 48 MiB | +7.6 GiB | +4.3 GiB |
| Unpacked size | 3.6 GiB | 170 MiB | +34 GiB | +9 GiB |
Add-on packages use so-called "extra-data". This means that during installation, several binary modules are downloaded from the original sources and merged with the Flatpak package. Due to this process, additional disk space is temporarily required when installing the add-on. Make sure you have enough disk space on the partition where flatpak applications are installed. When the Flatpak package is installed system-wide (default), the applications are stored in _/var/lib/flatpak_. In case of user installation (--user), the apps are stored in _~/.local/share/flatpak_.
Disk space required for the installation of the add-on package:
| **Add-on** | **Size** |
| --------------| ---------|
| AMD add-on | 55 GiB |
| NVIDIA add-on | 15 GiB |

### Beta version
In addition to the stable version in the Flathub repository, you can try to test the "Beta" version of the upcoming release. This version is usable, but may contain more bugs.
Beta version is available in "flathub-beta" repository. Follow [these instructions](https://discourse.flathub.org/t/how-to-use-flathub-beta/2111) to enable flathub-beta on your computer.
## Extra features
### Command-line options
The CLI interface is primary for the integration with the desktop when _Speech Note_ is already running (for example, hidden in the system tray or in the backgraund).
#### Examples
List all supported options:
```shell
flatpak run net.mkiol.SpeechNote --help
```
Start listening:
```sh
flatpak run net.mkiol.SpeechNote --action start-listening
```
Cancel any already started action:
```sh
flatpak run net.mkiol.SpeechNote --action cancel
```
Start listening, the decoded text will be saved to the clipboard:
```sh
flatpak run net.mkiol.SpeechNote --action start-listening-clipboard
```
Start listening, the decoded text will be inserted into any window on the desktop on which the cursor is focused:
```sh
flatpak run net.mkiol.SpeechNote --action start-listening-active-window
```
Start reading "Hello, how are you doing?":
```sh
flatpak run net.mkiol.SpeechNote --action start-reading-text --text "Hello, how are you doing?"
```
Save speech of "Hello, how are you doing?" to "speech.mp3" file:
```sh
flatpak run net.mkiol.SpeechNote --action start-reading-text --text "Hello, how are you doing?" --output-file speech.mp3
```
List all available TTS models:
```sh
flatpak run net.mkiol.SpeechNote --print-available-models tts
```
### Global keyboard shortcuts
Global keyboard shortcuts allow you to start listening or reading with the keyboard, even when the application is not active (e.g. minimized, hidden in the system tray icon or just in the background).
To enable and customize keyboard shortcuts, go to `Settings`->`Accessibility`->`Use Global Keyboard Shortcuts`.
In order for shortcuts to work under Wayland, your desktop environment must support [GlobalShortcuts interface](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.impl.portal.GlobalShortcuts.html) in the _XDG Desktop Portal_ service. Currently, `GlobalShortcuts` is supported only in the latest KDE Plasma and GNOME desktops.
When `XDG Desktop Portal` is used to manage global shortcuts, use the desktop environment tool to customize key bindings.
### Insert into active window
Using global keyboard shortcuts or command-line actions, you can directly start listening and insert the decoded text into any window that is currently in focus. This allows you to use _Speech Note_ as a voice typing tool on the desktop.
Under X11, this feature should work right out of the box.
Under Wayland, the external `ydotool` daemon must be installed and running for it to work. If you are using Flatpak, also make sure that the application has permission to access the `ydotool` daemon's socket file and the socket file.
### Subtitles
When transcribing (STT), you can also convert audio to subtitles instead of text. The supported format is SRT.
Subtitles are also supported in TTS. The reading aloud of subtitles is synchronized with the timestamps of the subtitles. If configured, the speed of the voice can be automatically adjusted to the duration of the subtitle segment. This allows you to create a voice-over from the subtitle file.
## Building from sources
### Arch Linux
It is also possible to build and install the latest development (git) or latest stable (release) version from the repository using the provided PKGBUILD file (please note that the same remarks about building on Linux apply):
```sh
git clone
cd dsnote/arch/git # build latest git version
# or
cd dsnote/arch/release # build latest release version
makepkg -si
```
### RHEL/Fedora/Rocky Linux
It is also possible to build and install the latest development version from the repository using the provided SPEC file and helper `make_rpm.sh` script:
```sh
git clone
cd dsnote/fedora
# optionally install build dependencies
dnf install rpmdevtools autoconf automake boost-devel cmake git kf5-kdbusaddons-devel libarchive-devel libxdo-devel libXinerama-devel libxkbcommon-x11-devel libXtst-devel libtool meson openblas-devel patchelf pybind11-devel python3-devel python3-pybind11 qt5-linguist qt5-qtmultimedia-devel qt5-qtquickcontrols2-devel qt5-qtx11extras-devel rubberband-devel taglib-devel vulkan-headers
./make_rpm.sh
```
### Flatpak
```sh
git clone
cd dsnote/flatpak
# build a base package
flatpak-builder --force-clean --user --install-deps-from=flathub --repo="" "/path/to/output/dir" net.mkiol.SpeechNote.yaml
# build an optional NVIDIA add-on package
flatpak-builder --force-clean --user --install-deps-from=flathub --repo="" "/path/to/output/dir" net.mkiol.SpeechNote.Addon.nvidia.yaml
```
### Sailfish OS
```sh
git clone
cd dsnote
mkdir build
cd build
sfdk config --session specfile=../sfos/harbour-dsnote.spec
sfdk config --session target=SailfishOS-4.4.0.58-aarch64
sfdk cmake ../ -DCMAKE_BUILD_TYPE=Release -DWITH_SFOS=ON -DWITH_PY=OFF
sfdk package
```
### Linux (direct build)
Speech Note has many build-time and run-time dependencies. This includes shared and static libraries,
3rd-party executables, Python and Perl scripts. Because of these complexity, the recommended way to build
is to use Flatpak tool-chain (Flatpak manifest file and [flatpak-builder](https://docs.flatpak.org/en/latest/flatpak-builder.html)).
If you want to make a direct build (i.e. without flatpak) it is also possible but more complicated.
```sh
git clone
cd dsnote
mkdir build
cd build
cmake ../ -DCMAKE_BUILD_TYPE=Release -DWITH_DESKTOP=ON
make
```
To make build without support for Python components, add `-DWITH_PY=OFF` in cmake step.
To see other build options search for `option(BUILD_XXX)` in `CMakeList.txt` file.
### Minimal Linux (direct build)
For developing features locally, going through the whole build process can be time-consuming; use this to make a minimal direct build.
```sh
git clone
cd dsnote
mkdir build
cd build
cmake ../ -DWITH_DESKTOP=ON \
-DWITH_PY=ON \
-DDOWNLOAD_VOSK=ON \
-DBUILD_VOSK=OFF \
-DBUILD_WHISPERCPP=OFF \
-DBUILD_OPENBLAS=OFF \
-DBUILD_RHVOICE=OFF \
-DBUILD_RHVOICE_MODULE=OFF \
-DBUILD_BERGAMOT=OFF
make
```
## Building WlClipboard
If you want to build wl-clipboard or if you do not have access to wl-clipboard in your system, and KDE Klipper or QClipboard are not working when you use simulated Ctrl+V when pasting text into the active window.
You can add this flag to build wl-clipboard:
```sh
cmake ../ -DWITH_DESKTOP=ON -DCMAKE_BUILD_TYPE=Release -DBUILD_WL_CLIPBOARD
```
## How to enable a custom model
All models available for download are specified in the configuration file (config/models.json).
To enable a custom model that is compatible with currently supported engines, simply edit this file and restart the application.
When you first run the application, the models configuration file is created in:
- `~/.local/share/net.mkiol/dsnote/models.json`, or
- `~/.var/app/net.mkiol.SpeechNote/data/net.mkiol/dsnote/models.json` (Flatpak), or
- `~/.local/share/org.mkiol/dsnote/models.json` (Sailfish OS)
You can freely edit currently enabled models or add new ones.
Model definition looks like this:
```json
{
"name": "",
"model_id": "",
"engine": "",
"lang_id": "",
"checksum": "",
"checksum_quick": "",
"comp": "
],
"size": ""
}
```
Allowed engine types: `stt_ds`, `stt_vosk`, `stt_april`, `stt_whisper`, `stt_fasterwhisper`, `tts_piper`, `tts_rhvoice`, `tts_espeak`, `tts_coqui`, `tts_mimic3`, `tts_whisperspeech`, `tts_sam`, `tts_parler`, `tts_f5`, `tts_kokoro`, `mnt_bergamot`
Allowed compression types: `none`, `gz`, `xz`, `tarxz`, `targz`, `zip`, `zipall`, `dir`, `dirgz`
Allowed URL types: `http`, `https`, `file`
Checksums are calculated for all files after unpacking. If you are adding a new model, you can use the `--gen-checksums` command line option to find the right checksums. To do this, put empty strings in both `checksum` and `checksum_quick`, save the file and run Speech Note with the mentioned option.
For example:
```json
{
"name": "New Piper Voice",
"model_id": "en_piper_new",
"engine": "tts_piper",
"lang_id": "en",
"checksum": "",
"checksum_quick": "",
"size": ""
"comp": "dir",
"urls": [
"file:///home/me/models/new-model-medium.onnx",
"file:///home/me/models/new-model-medium.onnx.json"
]
}
```
```sh
flatpak run net.mkiol.SpeechNote --verbose --gen-checksums
```
