How to Create Digital Speech Effects with a Synthesizer

What would you say if you could create your own digital speech effects with a synthesizer? It might sound inscrutable, but that’s what the voice-effect industry is working towards: a future where users don’t need to rely on artificial intelligence to replicate real human speech. To that end, many companies have begun developing AI services specifically for this purpose. In this article, you’ll learn how to create digital speech effects with a synthesizer. You’ll learn about various synthesis methods and how they work together to produce different sounds online pokies for real money. You’ll also discover why and when it’s helpful to include flourishes like accents and growls in your digital voiceovers.

What is digital speech?

Digital speech is the use of electronic devices to create realistic sounding speech. These devices can either generate speech directly or they can use software to generate human-like speech. While human-like speech is easiest to generate with a voice-modeller application or a voice synthesizer, real-time voice generation using a computer is also possible. Voice-modeller software allows you to create realistic human-like speech much more quickly and easily than a voice synthesizer. Synthesizers generate speech by sampling audio and then converting it to a format that a computer can process. A variety of synthesis methods are available, each with unique advantages and disadvantages.

Recreating human speech with a synthesizer

The process of creating a digital speech effect with a synthesizer is similar to that of creating any other type of sound effect. The main difference is that you don’t need to use a voice-modeller to create the sounds. With a synthesizer, you can generate any sound you can imagine. You may have heard people speak with an Australian accent or Mexican lilt. These are synthesized speech patterns created by a synthesizer.

In-range or off-axis synthesis

In-range synthesis places more emphasis on the directionality of the sound. It’s sometimes referred to as monophonic because the synthesizer only samples one note at a time. Off-axis synthesis, on the other hand, creates a more realistic sound by sampling multiple notes at the same time. This type of sound is often more musical and gives a more realistic impression of voice real money casino. It’s often used in voice-overs where the pitches should be higher than normal human voice and the timbre (the sound quality) is more balanced.

Grainier sounds

Grainy sounds are caused by having a low sample rate and a low bit rate. A low sample rate means that the computer is constantly sampling the same frequency of sound. With a low bit rate, the computer doesn’t “affect” the sounded frequency but only samples it and translates it to a digital value. As a result, the computer doesn’t generate the most musical sound. Instead, grainy sounds are usually heard with a lower bit rate, such as that of a vintage sampler. Grainy sounds are also known as “off-kilter” or “alien-sounding” and are commonly heard with speech that is unclear or unnatural.

Accent and growl effects

Accent and growl effects are a type of grainy sound that is created by adding a subtle pitch bend to the sound. However, unlike other types of grainy sounds, this effect is more aggressive. It’s used to add character and depth to otherwise ordinary sounds. Growls, which are also known asumannos, are the most common type of accent sound. A growl is the result of adding a low pitch to a high-pitched sound. The pitch of the growl should be low enough to fit within the voice range of an average-sized human but high enough to convey an animal-like sound.


Digital speech can be used to create realistic sounding speech, as well as to create text-to-speech functionality. A few examples of its use are in voiceovers where it’s helpful to include flourishes like accents and growls, and in media where a particular setting or location is being described. Research shows that people find the use of digital speech effects more engaging than using only real-time voice. With digital speech, you can create a more lifelike, 3D character with unique personalities and accents.
