Common FAQs

We’ve compiled the most frequently encountered user questions to help you resolve them quickly.

Question 1: Which languages does the software support?

AI Transcription for Mac supports over 90 languages for recognition and transcription. According to official technical documentation, its accuracy is highest for English, Chinese, Japanese, Spanish, and French. For Chinese, it supports Simplified and Traditional Chinese, and handles mixed Chinese and English content well.

Question 2: Why are some words in my transcription results inaccurate?

Transcription accuracy is influenced by various factors. First, check the audio quality, including background noise, distance from the microphone, and unclear speech. Second, industry-specific terms or obscure names might be misinterpreted. To address this, enable the “Custom Vocabulary” feature in settings to pre-define industry-specific terms. Lastly, ensure you are using the latest version 2.12, which has optimized the noise environment recognition algorithm.

Question 3: How long of audio files can the software handle?

Theoretically, there are no strict limits. However, in practical testing, handling audio files longer than 3 hours requires splitting them into 30-60 minute segments to reduce memory usage. The 2.12 version has improved memory management, allowing for smooth processing of files up to 2 hours long. For very long meeting recordings, consider batch processing.

Question 4: Why do the timestamps in the exported .srt subtitle files not match with the video player?

This is often due to inconsistencies in the video file’s frame rate or starting timestamps. To resolve this, confirm on the software’s timeline that the “Start Time” is set to zero before exporting subtitles. Alternatively, try exporting to the .webvtt format, which has better compatibility with time codes. If the issue persists, manually adjust the timeline’s start offset.

Question 5: Does the software collect my audio data?

No, it does not. AI Transcription for Mac uses a pure local processing engine, processing all audio files and transcription data solely on your Mac. The software does not require a network connection for audio analysis, only for downloading models or checking updates. This is clearly stated in the software’s user privacy policy, adhering to EU GDPR standards.

Question 6: Will my previous settings be lost after updating to version 2.12?

No, they won’t. The 2.12 version is an incremental update, preserving user preferences, custom dictionaries, and historical transcription records. The update process automatically backs up the original configuration files, allowing you to restore them from the “~/Library/Application Support/AI Transcription/” directory if needed.

Question 7: How does the software perform on Apple Silicon chips?

AI Transcription has been optimized for Apple Silicon (M1/M2/M3) chips. According to our tests, on the M2 Pro chip, transcribing a 30-minute MP3 file takes 4-5 minutes, which is about 40% faster than an Intel i7 processor. Additionally, due to local processing, battery life is also good.

Journalists often need to record in noisy environments. It’s recommended to use an external microphone and keep the distance within 30cm. After importing into the software, activate the “Noise Reduction” feature (added in version 2.12). If the speaker has a strong accent, switch to “Accent Enhancement Mode” in “Settings” > “Language Model” temporarily. Finally, use the “Timeline Control” feature to manually correct those key names or places that AI recognizes as fuzzy.

Tips 2: Batch Processing Meeting Minutes

For weekly team meetings, you can set up a workflow. Place multiple MP3 files in a folder. Open AI Transcription, click the “Batch Import” button. The software will automatically process each file in sequence and generate independent .txt documents. You can set up export templates to automatically insert metadata like date and meeting topics at the beginning of each document. According to a study in “Harvard Business Review,” this technique can reduce the time needed to compile meeting minutes by 70%.

Real-World Example: Creating Subtitles for YouTube Videos

Assume you are an educational YouTuber needing to add Chinese subtitles to a 30-minute English tutorial video. Here’s how to do it:

1. Drag the MP4 video file into AI Transcription.
2. In “Export Settings,” choose “Subtitle File” > “.sbv” format.
3. Let the software generate the original English text, then manually review and use the “Translate” feature (requires internet connection) to generate a preliminary Chinese version.
4. Adjust the Chinese subtitle times to ensure synchronization with the visuals. The 2.12 version added the “Waveform” feature, which helps you see the voice waveforms and locate key moments more accurately.
5. Export the .sbv file and upload it directly to YouTube. This platform natively supports the SBV format, eliminating the need for conversion.

The entire process takes about 45 minutes, whereas traditional manual transcription and translation usually take 4 hours. Based on feedback from our community, this workflow has increased video publishing efficiency by nearly three times.
