How to Use Audio to Text Tool

Upload Your Audio Files

First upload the audio files you want to convert to text. You can upload in two ways: drag and drop files to the upload area or click browse to select files. The tool supports WAV, MP3, FLAC, OGG, AAC, M4A and other formats. You can upload multiple files at once for batch processing.

We recommend using clear, noise-free audio files. Audio with moderate speech speed gives the best recognition results.

Preview Audio Files

After uploading, you will see all uploaded audio files in the left preview area. Each file shows file name, format and size information. You can click the play button to preview the audio and confirm you have selected the correct files. If you need to delete a file, click the delete icon.

For batch processing, we recommend previewing the audio list first to ensure all files to be converted are correctly uploaded.

Set Conversion Parameters

Before converting, you can adjust output settings. Select the appropriate Recognition Language (auto detect or manually specify), choose Output Format (TXT plain text, SRT subtitle file or JSON format), and optionally choose to Show Timestamp. These parameters help you get more suitable output results.

Manually specifying the language is usually more accurate than auto detection. We recommend manually selecting when the language is known.

Convert to Text

After setting up, click the "Convert to Text" button to start processing. The tool will process all uploaded audio files sequentially, showing progress information during batch processing. Conversion time depends on file size and quantity. Most audio can be completed in seconds to minutes.

Please keep the page open during conversion. Do not close the browser tab.

Preview and Edit Results

After conversion is complete, all converted text will be displayed in the right output area. You can view the recognized text content, each file showing word count and duration information. If needed, click the "Copy Text" button to copy content to clipboard for editing.

We recommend manually proofreading the conversion results, especially for technical terms and proper names.

Download Results

When satisfied with the conversion results, you can click the "Download TXT" or "Download SRT" button below each file to save individually, or use the "Batch Download (ZIP)" button at the top of the output area to package all converted text files into a ZIP file for one-time download. All processing is done locally in your browser, ensuring your audio privacy and security.

SRT format has timestamps and can be directly used for video subtitles; TXT format is suitable for general text processing.
