- Product
- Microsoft Clipchamp
- Device & OS
- not provided
- Scenario
- Generating voiceovers for video projects using the built-in text-to-speech feature.
- Observed behavior
- The AI voice produces an inconsistent pitch, sometimes sounding unnatural or excessively high-pitched, despite normal text input.
Before troubleshooting, ensure your Clipchamp project is saved and test your text script in smaller segments to isolate which specific words or phrases are causing the pitch inconsistencies.
Review the Script and Adjust Vocal Pitch Settings
Correcting script punctuation and manually adjusting the pitch settings can quickly resolve unnatural voice fluctuations.
AI voices heavily rely on text formatting to determine intonation. Missing punctuation or unusual slang can confuse the text-to-speech engine, causing sudden pitch changes.
Review your script for spelling errors, missing commas, periods, slang, or unusual wording that might confuse the AI generator.
Click on the generated text-to-speech audio track in your Clipchamp timeline to highlight it.
Navigate to the text-to-speech property panel located on the right side of the screen.
Locate the vocal pitch setting and change it from the default to 'Low', 'Medium', or 'High' to stabilize the output tone.

Switch to a Different AI Voice Profile
Some specific AI voices, such as BrianMultilingualNeural, may have inherent limitations with certain scripts.
Draft and Manage Your Video Scripts with WPS Office
While WPS Office does not edit video natively like Clipchamp, it is the perfect lightweight companion for drafting, organizing, and managing your video scripts to prevent AI voice issues. As a powerful Microsoft Office alternative, it offers seamless compatibility with Word, Excel, and PowerPoint formats.
- 1. Download and Install WPS Office: Get the free WPS Office suite from the official website and easily install it on your computer.
- 2. Draft Your Video Scripts: Open WPS Writer to carefully draft your text-to-speech scripts, utilizing the spell check tool to ensure perfect punctuation.
- 3. Save in MS Word Format: Save your completed scripts as .docx files, maintaining full compatibility with your existing Microsoft 365 workflows.

Frequently Asked Questions
Why does my Clipchamp AI voice sound like a chipmunk?
This usually happens due to inherent pitch inconsistencies in certain AI voice profiles, such as the 'Brian' voice. You can fix this by adjusting the pitch setting to 'Low' or switching to a more stable voice profile like 'Florian'.
How does punctuation affect AI text-to-speech?
Punctuation marks like commas, periods, and question marks dictate the rhythm, pauses, and intonation of the AI voice. Proper punctuation prevents the voice engine from speeding up or raising its pitch unnaturally during long sentences.
Where is the pitch control located in Clipchamp?
The vocal pitch control is located in the text-to-speech properties panel on the right side of the screen. It appears when you select your generated text-to-speech audio track in the timeline.
What should I do if changing the voice and pitch doesn't work?
If adjusting the vocal settings and rewriting the script does not resolve the inconsistent pitch, the issue may be a temporary glitch with the text-to-speech engine. You should contact Clipchamp Support for further assistance.
