FAQ

A: The text-to-speech audio is played using the speech synthesis capability of the current device. After authorizing recording of the current tab, the tool can capture the reading audio on this page and generate a downloadable audio file.

A: Please click “Authorize recording of current tab” again, select the current tab in the pop-up window, and confirm that tab audio sharing is enabled. Also check the system volume, page audio permissions, and whether the selected voice can read normally.

A: Yes. After selecting multiple TXT files and clicking “Read Files,” the tool will synthesize them one by one according to the file queue. Output file names use the original file names by default; if duplicate names occur, numbers will be added automatically to distinguish them. The results can be packaged as a ZIP for download.

A: The voice list comes from the current device and system speech services, so available voices may vary depending on the operating system, language packs, and browser environment. You can listen to a preview first, then choose a suitable voice.

A: Segmenting text improves reading stability, reduces interruptions in long text, and makes it easier to control pauses between segments. The tool splits content based on punctuation and the configured number of characters per segment.

A: It is recommended to set the background music volume to a low range, such as 10% to 25%. If the voice content is used for courses, narration, or announcements, clear vocals should be the priority.

A: MP3 has better compatibility and is suitable for video editing and everyday use; WAV preserves more audio detail and is suitable for post-production editing; OGG is usually smaller in size and suitable for some web or app scenarios.
