Audio Synthesis & Modification AI Tools 2024
Speech synthesis, also known as audio synthesis AI tools, can help an AI bot to turn text into speech using an artificial human voice. For example, consider bots which can read an article aloud to you. Or the chatbots that communicate with you on a website’s landing page.
All of this is speech synthesis. In short, you’re able to generate any speech from scratch.
A lot of tools nowadays allow users to convert any text-to-speech, or clone their own voice using a sample. Such tools include PlayHT, Murf AI, Synthesia, and more. Some of them are completely free to use, while others require a paid subscription.
Possibilities with these Audio AI Tools
All these audio generation AI tools hold a lot of possibilities and features. However, you may not be able to find each feature within one tool. And thus, different tools specify different features. Here are all the features offered by audio AI tools:
1. Audio Synthesis
Audio synthesis means text-to-speech conversion (basically, creating a speech from scratch using an artificial human voice). Tools with this feature allow you to enter your script and generate human-like audio.
2. Voice Cloning
Voice cloning allows you to ‘copy’ yours or someone else’s voice to generate a speech using that voice. In this case, you do the same as audio synthesis but now, with a cloned voice. Note that you have to upload an audio sample to clone a voice.
3. Background noise cancellation
Let’s say you have an audio with a lot of background noise and you wish you could clear that up. Well now you can. The “background noise cancellation” feature allows you to do the same.
4. Removing of “umm” “aa” words from speech
When we are stumbling upon words in a recording like, ‘um, ah’…it feels imperfect. Here, this feature allows you to remove all those breaks of your speech and make it flawless.
5. Voice Editing
AI voice editing is often used to modify human voices. These modifications are usually used to create unique and creative effects in speech dynamics.
6. Audio transcription
Some tools can also help you transcribe your audio or in simple words, generate captions. These are particularly helpful for videos.
7. Language Dubbing
As the name suggests, language dubbing replaces the actual dialogues of a video with translated dialogues. It’s often used to translate movies or TV shows into other languages.
Primarily use cases of these AI Tools
These audio AI tools are used in the following major ways:
1. Podcasts
Many tools have this feature that allows users to create, edit, and upload podcasts directly to streaming platforms like Spotify. Hence, you can use tools like Descript to start your new podcast!
2. Short and Long-form videos
Tools like Synthesia can help you create short-form and long-form videos with AI Avatars and audio synthesis. Additionally, you can add captions, making your videos even interesting.
3. Tutorials and Presentations
Some tools can also help you create tutorials and video presentations easily with audio and video generation AI tools.
4. Record/Transcribe Meetings
Tools such as Fireflies.ai can transcribe, summarise, and record your meetings with great accuracy. In fact, there are more similar tools that can act as your virtual assistant.
5. Audio Translation
As stated before, some tools allow for audio translation or language dubbing in videos. One of such AI tools is KUDO AI which can help you add captions and translate your audio.
6. Noise Cancellation
Lastly, tools such as Cleanvoice and CrumplePop can help you remove background noise and improve audio quality.

How AI Voices Work?
AI voices, or popularly known as ‘text-to-speech’ generation technology, work on the basis of three approaches — ML Algorithms, Natural Language Processing, and Speech Synthesis Technique.
Here, machine learning algorithms are the heart of the whole technology. The AI models are fed large datasets of human speech through supervised learning, serving as a rich source of linguistic patterns, phonetic structures, and speech dynamics. This helps the models to recognize the patterns and correlations between textual inputs and outputs.
Then comes NLP, which helps the AI models to understand and interpret human language. In addition, it allows AI to break down complicated sentences, grammar, and emotions.
Lastly, the Speech Synthesis Techniques allow AI voices to turn processed text into understandable and expressive speech. One of the popular techniques emerged is Text-to-Speech (TTS). Most of the tools nowadays use this technique, which makes the outputs more natural and expressive.
Limitation of Using these AI tools?
Here are several limitations of the AI audio generation AI tools:
- Since AI is heavily based on datasets, the outputs often lack creativity.
- The quality may not be good enough.
- AI voices may not capture the emotions and tones so well.
- The pronunciations might not be right.
Advantages of using these AI Tools
Now, let’s look at some advantages of AI audio generation tools:
- Good AI tools with amazing premium features can upgrade your content creation scale.
- The tools with the TTS technology are great at the speed and accuracy of outputs.
- Mostly, the AI-generated speech outputs are indistinguishable from human speech.
Endnotes
Just like AI tools are boosting efficiency and productivity, not using them can turn into a loss for the working people. It’s been over a year since they have captured the professionals, and even they suggest now to adapt to the change.
