TextyMcSpeechy

Make any voice into a Piper text-to-speech model

• Make a custom Piper TTS model out of your own voice samples or any existing voice dataset
• Learn how to convert a public domain dataset into another voice using an RVC model
• Learn how to make custom datasets from audio clips and text transcripts
• Use the dataset recorder to make fun TTS clones of your family and friends
• Listen to your voice as training progresses in a convenient training environment
• Rapidly train custom TTS voices by finetuning pretrained checkpoint files
• Now runs Piper in a docker container for much more convenient installation
• Includes original resources for creating custom pronunciation rules.
• Includes original guides for using custom Piper voices with Home Assistant
• 100% free, runs 100% offline.

This hobby project has gotten real press! How cool is that!?

News

February 24 2025 - fixed docs for manually editing voices to comply with Home Assistant's requirements

• My previous documentation of this process produced voices that worked in user scripts within Home Assistant, but I discovered that they would crash when used to create entities in Settings > Voice Assistants if fields set in the .onnx.json file differed even slightly from what was expected.
• I have updated the docs to correct this issue.
• This should not impact voices trained with the latest version of TextyMcSpeechy.

February 21 2025 - Piper-compliant filenames, improvements to workflow when training from scratch

• Voice models are now exported with filenames that comply with piper's naming convention (eg en_US-bob_1234-medium.onnx)
• .onnx.json files now have fields set correctly when exported
• These changes should make all models exported to tts_dojo/tts_voices usable in Home Assistant without modifications.
• Fixed issues with menus when resuming sessions that were intially trained from scratch

February 20 2025 - Improvements to multi-language suppport

• Training models from scratch (ie. without using pretrained checkpoint files) is now an option provided by run_training.sh.
• create_datasets.sh now stores the espeak-ng language identifier in dataset.conf so that there is no need to manually set a language during preprocessing.
• the language code needed to build filenames that comply with Piper's naming convention is also stored in dataset.conf.
• datasets created with earlier versions of TextyMcSpeechy will need to be updated: create_datasets.sh <dataset_folder>
• DATASETS/espeak_language_identifiers.txt provides clear directions about which language codes to use when setting up a dataset.

February 18 2025 - A new main branch appears!

• This brand new branch runs Piper in a docker container, which makes installation far, far, far, less painful.
• The scripts and docs in this branch have all been overhauled.
• The branch formerly known as main is now the non-containerized branch. It will be kept around for reference purposes but will not be maintained.

February 17 2025 - latest features:

• Layout of tmux training environment can now be saved by selecting the control console and pressing t. This layout will be applied automatically on subsequent runs.
• Custom pronunciation rules can now be defined in tts_dojo/ESPEAK_RULES. These can be applied automatically whenever the textymcspeechy-piper container launches via ESPEAK_RULES/automated_espeak_rules.sh.

Usage

Read the quick start guide to learn how to build datasets and train models.

Original guides in this repo:

• Customizing pronunciation
• Using custom voices in Home Assistant
• Rendering custom voices for Home Assistant on a networked device with a GPU

System Requirements

• A NVIDIA GPU with drivers capable of running CUDA is required. Training on CPU, while technically possible, is not officially supported.
• A hard drive with sufficient storage capacity for the base installation (~15GB) and checkpoint files generated during training. 50gb of free space is suggested as a practical minimum.
• This project is written entirely in shell script and is primarily intended for Linux users. Windows users will need to use WSL to run it.

Installation:

1. Check for currently installed Nvidia driver by running nvidia-smi. If something like the image below shows up, you may be able to skip to step 3
2. If Nvidia drivers are not installed on your system I recommend you do this using whatever "official" method exists for the distribution you are using. That's all the advice I can give you - in the past I have known the pain of spending hours repairing my OS after installing a driver I shouldn't have. If you survive this step continue to step 3.
3. Check whether Docker is installed on your system by running docker --version. If it is installed skip to step 5.
4. You can install Docker using the instructions here: https://docs.docker.com/engine/install/
5. You will need the NVIDIA Container Toolkit to enable GPU access within docker containers. https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html
6. Clone this repo:

git clone https://github.com/domesticatedviking/TextyMcSpeechy

7. To install packages, make scripts executable, choose the type of container you wish to run, and verify that needed tools are installed, from the TextyMcSpeechy directory, run

sudo bash setup.sh

8. Setup is complete. If you chose to use the prebuilt container from dockerhub it will download automatically the first time you use the run_container.sh script or start to train a model. Take note that it's a 6GB download and over 10GB when decompressed.
9. Continue with the quick start guide to begin training models.

Notes

• The prebuilt docker container will install automatically - You don't need to download it. But if you want to anyway, run this:

docker image pull domesticatedviking/textymcspeechy-piper:latest

• To build your own image from the Dockerfile and docker-compose.yml in the main TextyMcspeechy directory, change to that directory and run:

docker compose build

• Scripts are provided for launching the textymcspeechy-piper image, whether it is prebuilt or locally built.

  • local_container_run.sh launches images you have built yourself with Dockerfile and docker-compose.yml
  • prebuilt_container_run.sh launches a prebuilt image.
  • run_container.sh is a script that functions as an alias to one of the scripts above. It is called by run_training.sh to automatically bring the container up when training starts.
  • stop_container.sh will shut down the textymcspeechy-piper container if it is running.

• Custom espeak-ng pronunciation rules can be defined in tts_dojo/ESPEAK_RULES. A guide for customizing pronunciation can be found here.
