#1 UTAU

Freemium
Proprietary
Windows
Online

UTAU is a musical voice synthesis program that aids users in creating songs by typing in lyrics and melodies or by recording audio. You can make human-like voices or mimic existing ones, such as those of popular singers or characters. It can also be used to compile Ringtone-length voice clips from multiple voice samples. It uses a text-to-speech (TTS) vocal library created by the user and generates a melody using the selected voice.

The main difference between UTAU and other TTS programs is that UTAU allows users to create their own vocal library by hand instead of using preset voices; each vocal is made up of samples taken from a particular person’s voice. As such, it is possible to create new, realistic-sounding vocal samples using nothing but raw sound files from a person’s voice.

#2 VOCALOID

VOCALOID is a singing voice synthesizer software distributed by Yamaha Corporation that uses synthesizing technology with samples from voices of singers and speech sounds. The results of the work may be used for commercial purposes; however, the software must be acquired separately from the synthesized singing itself. There were three ways to use the software: singing synthesizing alone, singing plus melody synthesizing, and singing plus melody synthesizing plus rhythm synthesizing. The first two options have had the restrictions lifted.

A new feature is known as “extend” was added that allows users to import audio to be used as a basis for a vocal track. It uses sampled voices or vocal recordings from singers and uses them as the sound source for singing synthesizer technology. The software is capable of accurately imitating voices but also has the ability to be creative with those voices, such as changing their tone or adding accents. Each “voice” is actually a particular type of voice synthesis. In this sense, the word “vocaloid” can refer to both the software and the project.

#3 DeepVocal

DeepVocal is a fully open-source project that was made with the purpose of being able to remaster voicebanks. It is a new Chinese-developed vocal synthesizer that comes with a tool to help people create their own non-commercial voicebanks. Another goal of this program is to give people with no access to professional software the possibility to create their own voicebanks. One of the biggest issues with this, however, is that to properly use a vocal synthesizer, you need vocal samples.

To circumvent this problem, it has an integrated system to generate its own voice samples based on text input and some information about the sound that one wants. Currently, it supports Mandarin Chinese, English, and Japanese. The program also comes with a built-in tool that can help you edit existing voice banks and make them clearer, with less noise, and more suitable for your purposes. Unlike other voice synthesizers on the market, DeepVocal doesn’t rely on a pre-made database of sampled vocal sounds. Instead, it uses a neural network to generate a new voice from scratch. The app works best with plain texts, but you can also feed short poems or dialogues, which is not present in any other traditional platform.

To apply the new voice to the text, use your mouse to select the text first, then press play and select your new voice from the audio player.

It can change the pitch and speed at the same time and enables you to add lots of funny & crazy effects like Monster, Helium, Robot, and many more. This unique app has lots of voice-changing features that you can play around with, as well as 75+ effects to alter your voice. Some of the voice-changing effects include helium, robot, girl, old man, and even monster. The best part about this app is that it allows you to change your voice without having to spend time editing videos or pictures.

#5 eCantorix

eCantorix is a singing frontend for espeak, a software speech synthesizer that comes with the best results. It is based on the cantor text-to-speech software, which is a fork of Festival, which in turn is a fork of espeak. Cantor’s output backend support is limited to Festival, so it uses its own text-to-speech backend using espeak. eCantorix is a free, open-source software project to help people with speech disabilities use their voices to control a computer.

It’s a singing synthesis frontend for espeak, the open-source speech synthesizer that uses a text-to-speech engine to give people better control over the sound of their voices. It is useful for people who want to use Emacs, a text editor, as a singing synthesizer. eCantorix uses MPV as its video player and also provides a text-to-speech frontend that allows you to speak, sing or hum anything you want and have it sound like a real song. To install, run the command in Ubuntu terminal: sudo apt-get install ecanorix. This way, you can enjoy your favorite songs, compositions, or whatever you want.

#6 chipspeech

Windows
Online

chipspeech is a vintage-style speech synthesizer that recreates the sound of famous 80′s voice synthesis chips such as the legendary Texas Instruments Speak & Spell or the Commodore 64 voice. It was created as part of an in-house experiment to create fully-streaming audio effects, which can produce audio with very little delay, even on non-optimized mobile devices. From the classic robotic voice to designed robot speech, chipspeech will make your words come to life.

The synthesis is based on a cross-modulation between two analog oscillators. A change of the modulation frequency creates a cross-modulation frequency which is added to the main frequency of the first oscillator called carrier. This creates a deviation from the center frequency. Then, through a low pass filter and some audio amplifier, the synthesized speech sound is created.

#7 Alter/Ego

Alter/Ego is a vocal synthesizer that uses Artificial Intelligence like a human voice to create a realistic singing voice. It was designed with ease of use in mind. There are hundreds of presets to choose from, just click on any created by users, and you’re done. It has been used in professional productions for years, and the simple interface makes it easy to use for anyone.

With this platform, you can create your own processed vocal sounds, but it also includes more than 100 presets that have been created by different producers and engineers and gives you the option to control the character of your voice with a few simple controls. It includes a powerful polyphonic synthesizer, built-in effects, a Chromatic Tuner, a built-in sequencer, and recording functionality. For applying this program to the research field, it offers an open-source Python package that allows researchers to easily control their own computing environment.

#8 Sinsy

Sinsy is a singing voice synthesis program that can generate high-quality music with a distant human-like singing voice by using an online database of sentences as the training data and the Hidden Markov model-based automatic singing voice synthesis method. It is an open-source online singing voice synthesis system based on the popular library that allows fast and easy development of scientific computing code. It can synthesize singing voices from audio samples of speech and can also generate music from MIDI input. The framework makes the code very readable, which allows the user to quickly understand the functionality.

It has many libraries that provide functionality, such as accessing data from NumPy arrays, defining neural networks, and controlling GPUs. It is based on a sequence-to-sequence neural network model in which the segments of speech are modeled as hidden Markov chains. As for the speech synthesis, it employs a similar model where the segments of units are modeled as HMMs, but instead of one HMM, several HMMs are used and mixed together. This approach of mixing HMMs can generate a richer spectrum of singing voices.

#9 RenoidPlayer

RenoidPlayer is a web-based vocal synthesizer that runs on Renoise XRNI and SoundFont SF2. It features a browser-based user interface in which you can just type in the lyrics to your favorite song and within seconds hear your voice transformed into a humanized version of the original melody. It is loaded with eight different effects, including Compressor, Distortion, and Overdrive, so you can adjust the sound to suit your nasal vocals. It is a built-in Web Toolkit, a development framework that allows the creation of web applications using Java programming language. It can use the cepstral features of Renoise to create differently sounding vocals with each note.

It can also use the vocal samples included in the SoundFont pack, allowing much easier customization and adjustment of the sound. It is a polyphonic synthesizer with velocity layering, featuring 16 waveforms, frequency modulation, and linear/exponential envelopes.
