Improve the clarityof AI-generated speech
Change a setting, then hear the difference
Play the sentence at its default settings. Adjust speed or volume, then generate it again. Keep the words the same while comparing.
The interactive preview lets you edit a sentence and adjust speed and volume before generating it. You can also use these controls in Playground.

Speed and volume are generation guidance. The effect varies with the voice and text, so listen to a representative passage before choosing settings for your project.
Start with what you hear
A pronunciation problem needs a different adjustment from an audio-format mismatch. Change the part of the workflow that causes the problem.
A name sounds wrong
Add a pronunciation dictionary
Use sounds-like guidance or IPA for a recurring word. Listen to it within a complete sentence, not only in isolation.
The sentence feels rushed
Refine punctuation and speed
Shorten a crowded sentence first. If needed, lower the speed setting and compare the same passage again.
The delivery feels flat
Check the voice and script
Choose a voice suited to the language and intended tone. Add emotion guidance when it agrees with the words.
Playback sounds distorted
Check the audio format
Match the player's encoding and sample rate to the generated audio before changing the model settings.
How to improve an AI voice recording
A repeatable listening check helps you choose settings you can use again.
Keep the words fixed
Choose a sentence with the problem you want to fix. Include the names, punctuation, and phrases your audience will hear. Save the first result as your reference.
Change one setting
Keep the script fixed and adjust one setting, such as speed or a dictionary entry. If you compare voices, leave the other controls unchanged.
Listen in the destination
Compare the original generation with the new one through your player or phone connection. Check sentence endings and important words before saving the settings.
Keep the delivery consistent
Save the voice, transcript, and settings together. Reuse the same pronunciation dictionary for recurring names and technical terms across your recordings.
Guide the delivery
Use speed and volume to refine a voice that already suits the script. The controls guide generation, so compare a complete passage rather than expecting an exact change in duration or loudness.
Reuse pronunciations
Give a recurring name or technical term a dictionary entry. Test it in context, then apply that dictionary to later scripts so you can maintain the pronunciation in one place.
Choose the workflow for your audio
Create a new recording, compare languages, or choose a file format for playback.
Give difficult words a clear pronunciation
Listen to Sonic's pronunciation examples. For names and specialist terms in your own scripts, create a pronunciation dictionary and check each word in a full sentence.

Gaming
Generate character dialogue from your game's scripts. Compare voices for each role, then listen to new lines in context to check pacing and delivery.
Content
Create voiceovers for videos, tutorials, and product explainers from text. Revise a script and generate new narration without recording each line again.
Media
Turn written articles and stories into spoken audio. Use text-to-speech for podcast introductions or narrated news, checking names and pronunciation before publishing.
Healthcare
Read appointment reminders and patient service information from your team's reviewed text. Use a consistent voice for routine instructions and scheduling updates.
Sales
Add spoken narration to product demonstrations and sales explainers. Test your script in different voices, then update the audio when your product or message changes.
Voice Agents
Give AI voice agents spoken responses generated from your application's text. Choose a voice for greetings and conversations, then test how it sounds across short and longer replies.
Dubbing
Generate speech from translated scripts for your localization workflow. Compare voices in supported languages and review pronunciation and timing before adding the audio to a video.
Avatars
Pair a digital avatar with synthesized speech for presentations and guided experiences. Generate dialogue from text and coordinate audio playback with your avatar's animation.
Logistics
Turn shipment updates and dispatch instructions into spoken messages. Connect speech synthesis to your application so the audio reflects the latest delivery information.
Recruiting
Create spoken interview introductions and candidate scheduling messages from approved scripts. Keep instructions consistent and regenerate the audio when your hiring process changes.
Accessibility
Offer audio versions of written guides, articles, and learning materials. Let people listen to your content and follow along with the original text at their own pace.
Clone a voice to read new scripts
Create a reusable voice from a clean recording with AI voice cloning. Choose source audio with the tone and delivery you want, then test the clone on new scripts before refining the result.
Use your own voice or one you have permission to clone. Compare the original recording and its clone, then test your script to hear how the voice handles tone, accent, and pronunciation.
