Hello CapCut Team,
I am experiencing difficulties downloading and generating TTS speech. I have tried using a different account, but the problem persists, suggesting it might be a server issue. I have checked my internet connection, and everything seems to be functioning properly. This issue occurs on both the web and desktop versions of the application. Also, it is not generating the entire voice; it cuts 10 seconds before.
Could you please look into this?
Thank you!
Hi,
We understand it is challenging to have the TTS cut off early or failing to download completely really breaks the workflow. Here are a bunch of possible causes + troubleshooting steps you can try (some of which may confirm whether it’s indeed a server-side / backend issue). Let us know which ones you have already tried.
Possible causes
-
Backend / server-side glitch
Since you tried with a different account and on both web & desktop, it’s quite possible the TTS service endpoint (or its rendering / exporting backend) is having problems. -
Text-length / character limits
TTS services impose maximum length or duration limits (for example, only a certain number of characters or seconds). If your input is longer than allowed, it might get truncated. -
Timeout / throttling / process interruption
The TTS generation might be timing out mid-process (especially for longer text) or getting interrupted by network latency. -
Cache / local corruption / leftover temp files
Especially in the desktop version, some corrupted cache, temporary file, or local configuration might cause incomplete exports. -
Version or feature restrictions / bugs
There might be a bug in the version you have, or the feature can have a “pro / paid tier” change (such shifts can happen when new versions are released).
Troubleshooting steps you can try
Try these systematically, and check after each whether the issue persists:
| Step | What to Try | Why It Might Help / What to Observe |
|---|---|---|
| Clear cache / temp files / reset settings | In the desktop version, find the “clear cache” or “reset settings” option. Also delete any temporary export / render files. | If there’s corruption, it may allow the TTS engine to reinitialize correctly. |
| Update / reinstall | Make sure you have the latest version of CapCut on desktop & web. Uninstall & reinstall if possible. | Bug fixes or patches may resolve TTS issues. |
| Use shorter text / split text | Try with a short sentence (say 20–30 words) and see if it fully generates. Then gradually increase. | Helps isolate if the problem is due to length / timeout. If short texts work fine, it suggests the longer ones are hitting a service limit. |
| Try a different voice / language setting | Sometimes switching to a different TTS voice or language causes different processing paths. | If some voices work fully but others don’t, it hints that certain voice models are failing. |
| Test during different time / lower load | Try generating at off-peak hours (maybe when server load is less). | If it works sometimes but not always, that suggests server load / availability issues. |
| Check logs / error messages | If CapCut shows any error dialogs, logs, or status (on web dev console, desktop logs) when TTS fails or cuts off. | Might yield clues (timeouts, “service unavailable”, etc.). |
| Export audio-only / download separately | If the interface allows you to export just the TTS audio (without combining with video) or download it separately. | That helps isolate whether the issue is in the audio-generation pipeline vs the video export pipeline. |
| Contact support / submit bug report | Send detailed feedback to CapCut support (with project file, screenshots, timestamps). | If it’s server-side, CapCut team may already be aware and working on it. |
Workaround / alternative route
While the main issue gets fixed, you can try using an external TTS tool and then importing the generated audio into CapCut. This gives you control over length and reliability. Some alternatives:
-
Use an online TTS generator (Google Cloud TTS, Amazon Polly, Microsoft Azure, or free ones) to create full-length audio.
-
Download the audio file (e.g.
.mp3or.wav) and import it into your CapCut project. -
Align / trim / sync manually within CapCut.
This workaround is more manual, but ensures you get the full speech without relying on CapCut’s built-in engine.
Here are some alternative TTS / AI voice tools that closely match or blend well with what you would get from CapCut’s built-in voices along with tips on how to get good matching results. If you tell us which CapCut voice (accent / gender / style) you prefer, we can help you narrow further.
How to aim for matching CapCut style
Before listing tools, here are some voice characteristics and tweaks you should look for so the replacement voice sounds similar:
-
Natural / human-like intonation — CapCut TTS is “realistic & human voice” with smooth, expressive rhythm.
-
Accent / regional variant — If your target is “UK English” or “neutral English,” use TTS models that support that accent (some will default to US/UK).
-
Control over pitch, speed, pauses — Being able to tweak speed, pitch, and insert pauses helps you replicate the pacing CapCut uses.
-
Voice gender / timbre options — Choose male / female voices and pick ones with similar timbre to your CapCut voice.
-
Seamless export / good audio quality — The generated audio should be high bitrate (at least ~128 kbps) and clean (low noise or artifacts) so that when you import into CapCut, it blends naturally.
Recommended TTS / AI voice tools to try
Here are several good ones. Try generating an example script with CapCut’s voice and then compare with these to pick the closest match.
| Tool | Strengths / notes | How to use it (and tips) |
|---|---|---|
| ElevenLabs | Widely used in content creation; many customizable voice parameters. | Use the voice library, pick or clone a voice, adjust speed/pitch. Generate and download audio (e.g. MP3). Then import into CapCut. |
| Narakeet | Has English voices (male & female). | Use Narakeet’s English voices, test several, pick the one closest to CapCut’s tone. Download the file and add it to your CapCut project. |
| Podcastle AI | Good for video / voiceover workflows; supports English TTS voices. | Generate your script, preview different voices, export and use in your video editor. |
| VEED.io | Offers voice options in its built-in editor. | Use the TTS tool inside VEED, pick English, and export the audio for use in CapCut. |
| TTSMP3.com | Simple and free; supports English. | Paste your text, choose an English voice, download MP3, then bring into CapCut timeline. |
| Speechgen.io | Specifically geared to English accent generation. | Use the “English” mode, generate, listen, adjust speed or pause markers if possible, then export. |
| TTSMaker | Many voices and languages; easy interface. | Test a few voices to match CapCut style, export audio, then align in CapCut. |
Tips to make the imported TTS match more closely
-
After importing the audio into CapCut, adjust pitch / speed / fade to better match transitions and naturalness.
-
Sometimes adding a slight reverb or subtle audio effect (very mild) helps blend the TTS into the video environment so it doesn’t feel “detached.”
-
Break longer text into smaller segments and generate them separately, then stitch them in CapCut. This reduces chances of truncation and allows you to fine-tune each segment’s pacing.
-
For matching pauses and breathing, you can insert silent gaps (0.2–0.5 seconds) or use SSML (if the TTS tool supports it) to insert breaks.
