Applio vs. Kits: Multilingual TTS (and lip sync Face Swap!)

Introduction

Welcome back to the channel where we explore innovative applications of AI! In this article, we are going to compare two text-to-speech (TTS) technologies—Applio and Kits—that you can run on your own computer. Both of these tools allow you to create multilingual audio in your voice, or even clone someone else's voice. Additionally, we'll take this a step further by turning that audio into a multilingual video complete with lip sync using Face Fusion.

Overview of TTS Technologies

The two programs we're comparing today are Applio and Kits. While Applio is free, Kits does offer a free tier but requires payment for advanced features. Both of these tools allow you to train your own voice models and provide various voice conversion options.

Voice Cloning and Conversion

Both Applio and Kits enable voice cloning and conversion, allowing users to upload their own custom models. Applio primarily serves as the voice model creator and supports various text-to-speech technologies, while Kits utilizes stable voices and allows you to load models created in other programs.

The process of creating audio differs between the two. Applio requires generating an interim file through a two-step process: first, it creates an audio file based on the text you input, and then converts this file to your chosen voice model. Kits, on the other hand, streamlines this process by directly converting the text using your uploaded model.

Comparing Audio Quality

To compare audio quality using a specific voice—let's say "Bob Doyle High Energy"—sample texts such as meditation scripts are input into both programs. After initial tests, both systems yielded audio files with differing pitch and clarity. Adjustments in pitch settings allowed for fine-tuning to achieve a closer resemblance to the desired voice.

Multilingual Functionality

To utilize the multilingual capabilities, translated text is crafted using translation tools like Google Translate. When moving to different languages such as Japanese, German, and French, each program proved effective in generating coherent audio files. Specific voice models tailored to these languages were utilized to ensure quality.

Since audio quality can be subjective based on the listener’s familiarity with the language, it is recommended to rely on feedback from native speakers to assess which system performs better.

Lip Syncing with Face Fusion

After generating the multilingual audio files, the next step is using Face Fusion for lip syncing and face swapping. This software allows you to insert a new face into a target video while synchronizing the audio seamlessly. The key steps involve:

Importing the target video and the image of the replacement face.
Utilizing the audio files created earlier.
Following a systematic order to ensure the face swap, lip sync, and enhancement processes are applied correctly.

With the option for hardware acceleration, production time can be significantly reduced. Despite the complexity of the interface, default settings often yield satisfactory results.

Conclusion

This versatile workflow combining Applio, Kits, and Face Fusion demonstrates the potential of AI technologies for creating engaging multilingual content. By leveraging text-to-speech tools and lip sync capabilities, the creative possibilities are endless.
