Subtitles to Audio with Synchronized ai Speech

How Subtitle Dubbing Works with Neural Networks

Simply upload a subtitle file in SRT, SUB, VTT formats, select the language and desired voice, speech speed, and pitch. Click on the "voice subtitles" button and SpeechGen will automatically voice them using advanced neural network algorithms.

What you need to know

How it works. The neural network reads the subtitle format and determines the duration of the audio segment based on timing. For example, take this segment:
00:00:00,000 --> 00:00:02,500. It indicates that from the 0 second to the 2nd second and 500 milliseconds, the specified text needs to be voiced.

If SpeechGen understands that it cannot complete the voicing at normal speed within this period, it accelerates the speech to fit within the specified time frame. However, for a pleasant sound, the system has a limitation on the maximum acceleration. If voicing the interval requires speeding up the speech more than 3 times, a validator will issue a warning.

This actually happens due to not quite accurate subtitles and differences in word length in different languages. You can manually correct the problematic section or force SpeechGen to voice it at any speed.

Directive to ignore the speed limit. Place the hash symbol # at the beginning of the line, and SpeechGen will forcibly voice this text at any speed and fit into the timing at all costs. However, for the best quality of dubbing, we recommend adjusting the time interval of the previous and current subtitle block to more evenly distribute the acceleration.

Hide unnecessary text from voicing with square brackets. If you want to omit part of the dialogues but not lose the pace, then highlight the entire block of text like this: [ ]. SpeechGen will ignore everything indicated in the square brackets, but the timing will be observed.

Adhere to the format of each file type, otherwise, our system will not be able to synthesize speech correctly. For example, if in srt you miss a comma before the milliseconds like this 00:00:02500, SpeechGen will think it is a number to be read. The comma may disappear if translating subtitles through Google Translate.

On this page, SpeechGen is linked to str, vtt, sub formats. Therefore, for regular texts, use the standard page online voicing.

Text line breaks within a single timing block are voiced as one sentence. Place periods where necessary so the system understands the sentence has ended.

Is multi-voice voicing available?

Yes, you can generate speech with different voices. However, only 1 voice can voice a single line within the timing. Add the desired voice through the "add voice" button and fully encase each dialogue within a single subtitle block. If done incorrectly, the system will alert you.

You can choose an additional voice in any language. However, make sure that the subtitles are text and alphabet in that language.

Are Limits (credits) deducted for technical information SRT, SUB, VTT?

No, the system understands where technical information is indicated and does not account for this when deducting limits. However, at the bottom of the voicing field, you see a "Character count" mini-calculator, which primitively counts all characters. Don't worry, the system does not rely on this information, but uses its own, more complex algorithm. You can verify this by checking the actual deduction of Limits in the profile.

Is there economical caching?

Yes, when creating off-screen voice-over for videos, SpeechGen caches each sentence. If the voicing is repeated, the system will only deduct limits for the changed sentences.

Change the subtitle timing - repeating voicing with the same text will be free. The system accelerates voicing by its own algorithm. If you need to fit into a new interval, SpeechGen does not re-voice but simply boosts the speed. So edit the subtitle intervals without fear of extra expenses.
