Working on Audiobook Maker with Realistic Voices

Introduction

Introduction

Today's live stream revolved around integrating the RVC (Real Voice Cloning) pipeline into an audiobook maker, using TTS (Text-to-Speech) engines like Tortoise TTS. This integration aims to generate audiobooks with more realistic voices, incorporating models trained on user-specific data.

Debugging and Installation

Initially, I faced a few debugging challenges. The primary goal was to install dependencies and ensure that torch, tortoise, and RVC pipelines were correctly set up in the virtual environment.

pip install torch
pip install tortoise
pip install my_rvc_pipeline

Key Libraries

• torch for running machine learning models.
• tortoise as the TTS engine.
• RVC for voice conversion.

Configuration and Testing

I set up a Python script to test if the TTS and RVC integrations were functioning correctly. The initial test script didn't work due to issues with referencing paths and packages, but after setting up the correct paths and confirming the presence of required packages, the integration started working.

from rvc_infer import RVCConvert
from tortoise_api import TortoiseAPI

model_path = "path/to/model.pth"
input_path = "path/to/input.wav"
output_dir = "path/to/output/"

api = TortoiseAPI()
response = api.call("Test String")

rvc = RVCConvert(model_path=model_path, input_path=response, output_dir=output_dir)
rvc.convert()

Creating a Git Repository

In order to maintain the newly created code and for version control, I initialized a Git repository.

git init
git add .
git commit -m "First commit"
git remote add origin <repository_url>
git push -u origin master

Voice Model Configuration

Various models and voice configurations were tested to get the optimal voice quality for the audiobook. The models used included Dewey 48k, Mel, and some other pre-trained voices.

voice_name: "Dewey 48k"
model_path: "path/to/Dewey_48k.pth"

Problems Encountered

• Permission issues: Initially, the script threw Permission Denied errors which were resolved by ensuring proper reading and writing permissions.
• Audibility issues: Some trained models produced voices that were either too high-pitched or too deep. These were adjusted using the transpose parameter in the RVC pipeline.

Future Plans

1. Parameter Adjustments: Make the script more user-friendly by allowing easy parameter changes.
2. GUI Integration: Integrate with Gradio for a graphical user interface.
3. Additional TTS Engines: Incorporate other TTS engines for more versatility.

Conclusion

The integration of the RVC pipeline into an audiobook maker aims to create more natural-sounding audiobooks. Despite some initial challenges, the proof of concept worked well, and future improvements will make the tool more robust and user-friendly.
