The subtitles say

What does the subtitle say?

The subtitles state that it is an AI tool for audio-text synchronization used in video post-production, capable of generating SRT subtitle timelines from existing audio and finalized script text.

It addresses the issue of having the text content ready but lacking accurate subtitle timing; it is not an ordinary text-to-speech tool.

Main functions

• Upload the audio along with the final text version.
• Automatically matches the timing of text and speech.
• Generate a millisecond-level SRT subtitle timeline.
• Reduce errors in proper nouns and characters with multiple pronunciations.
• It supports the creation of video subtitles for existing scripts.
• Alignment methods such as spaced processing are provided.
• New users can receive a free trial period in minutes.
• Professional alignment packages with long duration are available.
• The account stores task and result records.
• The text-to-speech synthesis feature is in a limited beta phase.

Which users are it suitable for

The difference between phoneme alignment and speech recognition

How does text-alignment work?

The system uses the text provided by the user as a reference to locate the starting and ending points of the corresponding phrases in the audio, and then generates subtitle blocks.

Therefore, the accuracy of the text depends on the final version of the script, while the accuracy of timing is influenced by the quality of the recording, the consistency of pronunciation, and sentence breaks.

1. Prepare the final version of the spoken script.
2. Export clear original audio.
3. Verify that the order of the recordings matches that of the text.
4. Upload the audio and paste the text.
5. Select the appropriate alignment settings.
6. Submit the task and wait for it to be processed.
7. Preview subtitle timing and punctuation.
8. Correct missed readings, additional readings, and pause positions.
9. Export an SRT file for editing.

How to prepare audio

How to prepare copywriting

The closer the text is to the actual spoken content, the more stable the alignment will be; punctuation and paragraphing also affect the reading rhythm of the subtitle blocks.

• Use the version that was actually used during recording.
• Delete unread titles and annotations.
• Fill in the phrases that actually appear in the recording.
• Standardize the spelling of numbers, units, and proper nouns.
• Make natural pauses according to the meaning and speech pace.
• Do not include time codes or irrelevant explanations.
• Long documents are processed in batches, chapter by chapter.

What are SRT subtitles?

SRT is a common subtitle format; each subtitle block contains a sequence number, start time, end time, and the text to be displayed.

Once generated, it can be imported into most video editors and players, but the font, color, and position usually need to be set in the editing software.

Interval and pause handling

Pauses, breaths, and blank sections in a speech affect the way subtitle segments are divided; it’s not sufficient to rely solely on whether the text is identical.

• Short pauses can be retained within the same subtitle block.
• A new subtitle block is suitable to be created at the end of a semantic unit.
• The previous subtitle should be ended in time before a long pause.
• The background music segments should not be forced to match the text.
• The opening and closing sequences can be processed separately in video editing software.
• After exporting, check the synchronization again at the final frame rate.

Free quota and professional packages

The current homepage offers a 100-minute trial period free of charge upon registration, and it also displays a professional package that costs 125 yuan for 30,000 minutes of service.

The specific validity period, refund policies, invoices, and usage restrictions are subject to the purchase page and settlement rules available after logging in.

How to view the old membership rules?

The old official member page still shows that a deposit of 100 yuan grants 10,000 points and makes one a lifetime member, as well as highlighting previous benefits such as text-to-speech functionality.

Since the current homepage indicates that text-to-speech synthesis is available only as a limited beta feature, the rights and benefits of the old version cannot be considered as guarantees for the new version.

Current status of text-to-speech synthesis technology

On the current homepage of the official website, TTS is labeled as “coming soon” or “limited beta version”; therefore, regular users cannot assume that it is already fully available.

• Do not commit to the current number of speakers based on the information in older articles.
• Do not assume that TTS can be used before making a payment.
• The eligibility for the beta test, as well as the audio quality and data allowance, may vary.
• For commercial use of voiceovers, it is necessary to check the current licensing terms.
• The benefits associated with the old account should be verified separately after logging in.

How should “100% accurate” be understood?

The claim of 100% accuracy on the official website is a marketing statement; it mainly serves to emphasize that the subtitles use the final text provided by the users.

It does not guarantee accuracy in terms of timeline, sentence segmentation, handling of missed parts, and across all audio conditions; manual verification is still required before publication.
