tortoise.cpp: GGML implementation of tortoise-tts (Support Development Here!)

a menacing sea turtle in the ocean; mascot for tortoise.cpp

Downloading

clone the repository with the following command

git clone --recursive https://github.com/balisujohn/tortoise.cpp.git

Compiling

For now, CUDA and CPU only. To compile:

Compile for CPU (works on Linux x86 and Mac ARM)

mkdir build
cd build
cmake .. 
make

This is tested with mac os arm

Compile for CUDA

mkdir build
cd build
cmake .. -DGGML_CUBLAS=ON
make

This is tested with Ubuntu 22.04 and cuda 12.0 and a 1070ti

Compile for Mac OS with metal (work in-progress)

mkdir build
cd build
cmake .. -DGGML_METAL=ON
make

Running

Only lowercase letters, spaces, and punctuation are supported in the prompt.

You will need to place ggml-model.bin, ggml-vocoder-model.bin and ggml-diffusion-model.bin in the models directory to run tortoise.cpp. You can download them here https://huggingface.co/balisujohn/tortoise-ggml. I will release scripts for generating these files from tortoise-tts.

From the build directory, run:

./tortoise

here's an example that should work out of the box:

./tortoise --message "based... dr freeman?" --voice "../models/mouse.bin" --seed 0 --output "based?.wav"

all command line arguments are optional:

arguments:
  --message           Specifies the message to generate, lowercase letters, spaces, and punctuation only. (default: "this is a test message." )
  --voice             Specifies the path to the voice file to use to determine the speaker's voice.  (default: "../models/mol.bin" )
  --output            Specifies the path where the generated wav file will be saved.                 (default: "./output.wav")
  --seed              Specifies the seed for psuedorandom number generation, used in autoregressive sampling and diffusion sampling (default: system time seed)

How to add voices

set up the original tortoise-tts, then run it with whatever voice you have, then after this line: https://github.com/neonbjb/tortoise-tts/blob/e2d9fba0bb5c4376d0d142efea47a448f97c4d90/tortoise/api.py#L401

add this code:

numpy_array = auto_conditioning.to("cpu").numpy().astype(np.float32)  # Ensure float32 for binary format

# Define the file path
file_path = 'auto_conditioning.bin'

# Save NumPy array as binary file
numpy_array.tofile(file_path)

print("saved auto conditioning")
exit()

then you can rename auto_conditioning.bin to the speaker name and put the file in your models folder to use it like any other voice. This works with voices clone with tortoise-tts.

Contributing

If you want to contribute, please make an issue stating what you want to work on. DM me on twitter if you want a link to join the dev Discord, or if you have questions. I am happy to help get people get started with contributing!

I am also making available a fork of tortoise-tts which has my reverse engineering annotations, and also the export script for the autoregressive model.
