How to Make An AI Voice Model: A step-by-step Guide

Have you ever wanted to learn how to make an AI voice model? One that sounds just like you or whoever you choose? Believe it or not, developing a personalized synthetic speaking voice is now quite achievable, even for non-experts.

In this guide, we’ll break down the straightforward process step-by-step. From collecting voice recordings to training machine learning models, you’ll see how simple it is to clone or emulate a target voice through computational methods.

Understanding AI Voice Generation

AI voice generation is a groundbreaking technology that leverages machine learning to synthesize human-like speech from written language.

First, the text is broken down and tagged with linguistic metadata to understand word meanings and relationships. Then, a phonetic transcription is produced to map out the speech sounds. Complex algorithms shaped by vast training datasets then synthesize the ultimate waveforms to be converted into high-fidelity audio.

The applications of AI voice technology are truly far-reaching. Automated conversational assistants like Siri, Alexa, and Google Assistant integrate these AI voices to communicate with users through natural language. Customized voices also enhance e-learning, marketing campaigns, and a variety of multimedia experiences through AI-generated speech.

How to Make An AI Voice Model in 1 Minute?

Let’s take Kits AI as an example. Here are some steps of how to make an AI voice model in about one minue.

Step 1: Creating an Account

To get started, you will need to sign up for a free Kits AI account using Google or social media. You can simply click on the “Get Started” button to register an account.

Step 2: Clone A Voice or Blend AI Voice

Then, you can either pick a preset voice from their library or customize one by blending two samples together. This allows you to tailor the voice to your specific preferences.

Step 3: Adjust the pitch of your input audio

An important next step is adjusting the pitch of any input audio to match the chosen voice model precisely. This step ensures the AI accurately mimics the target voice timbre.

Step 4: Generate a Video Script

Finally, use the text-to-speech feature to produce a video script using the new AI voice. This handy tool lets you create high-quality audio tracks and clips without worrying about copyright issues.

Creating Your Own AI Voice Model Easily from Scratch

Developing your own custom AI voices takes some work, but with the right steps and patience, it’s quite doable.

Step 1: Gather Voice Samples

The first step is gathering pristine voice samples of the speaker you want to emulate. Record various pitches, tones, and styles to capture their full range. Be sure any background noise or volume inconsistencies are cleaned up.

Step 2: Choose a Voice Cloning Tool

Now, do your research to pick a voice cloning tool, like Kits AI, Voicify, or RVC, both are solid options. For example, Kits AI lets you blend different voices or train entirely on your own data set.

Step 3: Upload and Train

Upload your dataset, select a time slot, and let the AI get to work analyzing speech patterns and linguistics. Then comes the fun part of tweaking your synthetic voice to perfect the tone, pace, and character.

Step 4: Fine-tune and Test

Test it out by converting new audio and listening to how naturally it mimics the original. With a little trial and error, you’ll soon have your very own personalized AI voice model ready to use.
