🎤 Preparing High-Quality Voice Model Data

To train a high-quality voice model, you need to provide 10 minutes of clean, dry monophonic vocals without any backing tracks, time-based effects like reverb and delay, or any harmonies and doubling. The data set should be recorded using a high-quality microphone in a lossless file format to ensure the best results. The model captures every detail from the data set and uses it to create realistic audio conversions. It's crucial to avoid background noise, hum, and lossy compression artifacts, as they can degrade the model's quality. The data set should also include a wide range of pitches, vowels, and articulations to cover all sounds the model will need to convert. Original recordings of the target voice, such as studio acappellas, are ideal, but if not available, the kits vocal separator tool can be used to extract vocals from a master recording. The tool can also clean up vocals by removing reverb, echo, and harmonies. Once 10 minutes of good training data is compiled, it can be uploaded to kits for training.

Keywords

💡AI Voice Cloning

AI Voice Cloning refers to the technology that allows the creation of a synthetic voice that closely resembles a specific individual's voice. In the context of the video, it is the process of training a voice model using a dataset of vocal recordings to replicate the voice's unique characteristics. The video emphasizes the importance of using high-quality, dry monophonic vocals for training to achieve a realistic conversion.

💡Dry Monophonic Vocals

Dry Monophonic Vocals are recordings of a single voice without any additional musical accompaniment or effects. The video script specifies that these vocals are necessary for training an AI voice model because they provide a clear and unadulterated sample of the voice. This helps the AI to learn the nuances of the voice without interference from other sounds.

💡Training Data

Training Data is the set of vocal recordings used to teach the AI system how to replicate a particular voice. The script mentions that 10 minutes of dry monophonic vocals are needed for a high-quality voice model. The quality of the training data directly impacts the quality of the voice model, making it crucial to use clean, high-fidelity recordings.

💡Lossless File Format

A Lossless File Format is a type of digital file storage that retains all the original quality of the recorded audio without any compression or data loss. The video emphasizes using such formats for training data to ensure the highest possible quality of the voice model, as lossy compression can introduce artifacts that degrade the model's performance.

💡Vocal Separator Tool

The Vocal Separator Tool is a feature within the Kits.AI platform that allows users to extract the main vocal track from a master recording. This tool is useful for isolating vocals when original recordings are not available, as it can remove background music and other non-vocal elements. The script illustrates its use by showing how one can drop a file or paste a YouTube link to separate vocals.

💡Reverb and Delay

Reverb and Delay are audio effects that can add depth and space to a recording by simulating the natural reflections of sound in a physical environment. However, the video script advises against using these effects in the training data because they can cause overlapping voices and lead to misinterpretation by the AI, resulting in glitches in the voice model.

💡Harmony and Doubling

Harmony and Doubling refer to the musical techniques where multiple voices or instruments sing or play the same or related notes simultaneously. The script cautions against including these in the training data because the AI voice model might mistake them for the original voice, which can cause artifacts and glitches during the conversion process.

💡Pitches, Vowels, and Articulations

Pitches, Vowels, and Articulations are the fundamental components of speech that give a voice its unique sound. The video script suggests including a wide range of these elements in the training data to ensure that the AI voice model can accurately replicate every sound the user wants to convert. This comprehensive coverage helps in creating a more realistic and versatile voice model.

💡Conversion String Slider

The Conversion String Slider is a feature within the Kits.AI platform that allows users to adjust the conversion process of the audio. By experimenting with this slider, users can fine-tune the output to achieve the desired sound quality. The script does not provide specific details on how the slider works but implies that it is part of the customization process for audio conversion.

💡Dynamic Slider

The Dynamic Slider is another adjustable feature in the Kits.AI platform that likely affects the dynamic range or other aspects of the audio conversion process. The video suggests using this slider, along with pre- and post-processing effects, to optimize the sound of the converted audio. It is part of the customization tools that enable users to achieve the best results from their voice model.

💡Text-to-Speech Feature

The Text-to-Speech Feature enables users to input text that the AI voice model will then speak aloud. This is a useful tool for testing the voice model's capabilities and ensuring that it can accurately reproduce the intended speech. The script mentions this feature as a way to quickly test new models or conversion settings without using up conversion minutes.

💡Convert Minutes

Convert Minutes refer to the allotted time or capacity for converting audio using the AI voice model. The video script indicates that users can convert a significant amount of audio without using up their convert minutes, suggesting a generous allowance for users to experiment with the voice model and conversion settings.
