What Are AI Text-to-Speech Voices?
AI text-to-speech voices are digital profiles built to convert written text into spoken audio. Rather than stringing together individually recorded words, neural voices understand phonetics, rhythm, and pronunciation, allowing them to read full sentences naturally.
To learn more about the technical process behind this synthesis, read our guide on how text-to-speech works.
English Voices Available in Konthora
Konthora currently exposes 10 verified English voices to support a variety of audio workflows. These are split into two major accent groups: American English and British English.
American English Voices
There are 6 American English voices available, providing a standard North American pronunciation style.
British English Voices
There are 4 British English voices available, offering a traditional UK pronunciation style.
How to Choose the Right Voice
Choosing the right voice depends on the context of your project. Because neural models generate audio based on how they were trained, certain voices naturally fit different styles of content:
- Target Audience: Select an accent (American or British) that aligns with your primary listeners. An American voice reading British slang or spellings may sound slightly unnatural.
- Content Tone: Some voices have a brighter, faster delivery suited for social media or marketing videos, while others have a steady, measured pacing better suited for e-learning, audiobooks, or documentaries.
- Clarity: When generating technical scripts or complex terminology, you may need to preview several voices to see which one handles the specific jargon most clearly.
How Playback Speed Changes the Result
In addition to picking a voice, you can heavily influence the final result by adjusting the playback speed. Konthora allows you to modify the speed from 0.75× (slower) up to 1.25× (faster).
Slowing a voice down can make complex instructions easier to follow, while speeding a voice up can create a sense of urgency or energy. Because the AI is actively rendering the speech, these adjustments preserve pitch and clarity much better than simply speeding up a traditional recording.
How to Preview and Generate Speech
All 10 voices are available to test in the text to speech workspace. The platform uses a browser-based workflow, meaning you can generate audio immediately without creating an account.
When using the workspace, remember that generations are limited to 2,000 characters per request to ensure optimal performance. You can export your final voiceover as an MP3 or WAV file.
Note: Audio files are generated dynamically and stored temporarily. For privacy and security, they are not kept permanently on the server. You must download your generated audio during your active browser session.
