Dubverse

What is Dubverse?

Dubverse is an AI-based multilingual voice-over and subtitle platform designed for video creators, educational institutions, marketing teams, and businesses. After users upload videos or import content, the platform can automatically transcribe the original audio, translate the text, select the target language and an AI voice actor, and then generate voice-over videos, audio files, or subtitle files.

The platform divides its functions into DUB, SUB, and SAY: DUB is used for translating and dubbing videos, SUB is used for transcription and subtitles, and SAY is used for converting text into speech. Advanced versions also offer voice cloning, priority processing, custom subtitles, and improved translation models.

If developers need to synthesize speech in bulk within their applications, they can use a separate TTS API; the pricing for characters used with this API differs from that of the credits available on the web interface.

Core features of Dubverse

AI video dubbing and translation

Dubverse can identify speech from videos, create segmented scripts, translate them into the target language, and generate new audio tracks. Users can modify the text in Advanced Studio, redo specific sections, repeat segments, and adjust the speaking pace.

Machine translation may misinterpret names, brands, slang, and context; it should be reviewed by someone familiar with the target language before being published.

Automatic subtitles

The SUB function converts video audio into subtitles on a timeline, and it supports various animation styles as well as common output formats for subtitles. Automatic transcription can be affected by accents, background noise, multiple speakers speaking at the same time, and specialized terminology; therefore, when creating subtitles it is necessary to pay attention not only to the text itself but also to sentence structure, the length of each line, the timing of their appearance, and the reading speed.

AI text-to-speech

SAY can convert scripts into AI-generated audio, which is suitable for voiceovers, courses, advertisements, and broadcasts. Users can choose from various speakers and adjust the segments according to the specific context.

Using SAY alone requires fewer credits compared to providing a full video narration; if an accurate translation is already available, it is usually more cost-effective to have only the audio track.

Voice cloning

Supreme and its corresponding premium services offer voice cloning capabilities, enabling the generation of a speaker’s voice in different languages. The higher the quality of the recording sample and the more stable the tone, the better the result will be.

Voice cloning requires explicit permission from the individual; it is not allowed to impersonate public figures, employees, customers, or relatives, nor can it be used for fraud or to bypass identity verification.

Multiple speakers and enterprise localization

The enterprise solution offers features such as multiple speakers, lip-syncing, human review, customized AI models, and end-to-end media management; it is suitable for the large-scale localization of course libraries, film and television content, and brand videos. In multi-speaker scenarios, it is necessary to properly separate the speakers and maintain a consistent voice tone for each character, and complex projects usually require manual quality inspection.

Studio editing and export

The paid plans offer options such as watermark-free content, unlimited downloads, project history, the ability to customize transcripts, and support for various subtitle formats. The maximum length of the videos that can be exported, the styles of subtitles, the processing priority, and the rules regarding the retention of projects vary depending on the chosen package.

For important projects, the original manuscript, the revised version, the authorization documents, and the final product should be kept.

Comparison of prices for Dubverse creator packages

The following shows the minimum monthly pricing available on the official international pricing page; the currency is the US dollar, and each plan includes 50 credits as an example. The page also allows selection of 50, 100, 500, or 1,000 credits, as well as longer payment periods. The actual total cost varies depending on the region, taxes, payment period, and credit amount.

The discount for long-term plans is subject to the settlement page.

Comparison of Dubverse Credits Usage

Credits for the 30-day plan are usually issued in a single installment, while those for the 180-day plan are issued on a monthly basis. Additional credits can be purchased on the platform, but such additional amounts do not extend the validity period of the plan automatically.

The help center states that there is a 10-day window for renewal after the subscription expires; if this window passes, any unused credits will become invalid.

Check the current rules again before making a formal purchase.

Comparison of prices for Dubverse TTS API

The TTS API is charged based on the number of characters processed, rather than using minutes of credit as in the web interface. The official documentation provides 5,000 characters for free testing; for higher usage volumes or audio outputs exceeding 100 minutes, it is possible to request a bulk quote.

How to choose between Pro and Supreme?

For basic short-video translation, simple subtitles, and standard audio settings, Pro is sufficient; choose Supreme when you need voice cloning, longer videos, priority processing, custom subtitles, or improved translation capabilities.

Before making a selection, it is necessary to calculate the credits based on the actual duration of the video: for example, 10 minutes of fully dubbed video require around 40 credits, while generating subtitles for the same content only requires about 10 credits.

When a team needs multiple roles, manual proofreading, lip-syncing, custom sound tones, or batch system integration, a Creator subscription is usually not sufficient; in such cases it is advisable to compare the features offered by Enterprise with those of the TTS API. Do not purchase a large number of credits just for a particular advanced feature, ignoring the maximum duration allowed for the project and the licensing requirements.

Dubverse Video Translation and Dubbing Tutorial

1. Prepare the video:Use source files with clear vocals, low background music, and minimal overlapping speech.
2. Select DUB:Upload a video or use the import methods supported by the platform to specify the source language and target language.
3. Check transcription:First, correct the names, brands, numbers, terms, and paragraphing, before starting the translation.
4. Proofread translation:Maintain the original meaning and conversational length, avoiding overly long translations that might cause the speech to speed up or go beyond what is visible on screen.
5. Select speaker:Listen to the audio based on the character’s age, tone of voice, and type of content; in multi-person videos, the character assignments remain consistent.
6. Generate preview:First, process the short segments by checking pronunciation, rhythm, volume, subtitles, and lip movements.
7. Local redo:Use range redo and paragraph editing to fix issues, avoiding the waste of quota by re-creating the entire project repeatedly.
8. Export quality inspection:Download the finished product and subtitles, and check on mobile and desktop devices for synchronization, image quality, and safe areas.

Subtitling tutorial

1. Select SUB and upload the audio and video to confirm the source language.
2. Generate post-transcriptional, sentence-by-sentence correction of the text and speaker.
3. Translation should be carried out only when multiple languages are needed, and it must be reviewed by someone who speaks the target language.
4. Adjust sentence breaks, timelines, characters per line, and subtitle styles.
5. Export the video or subtitle files, and check the compatibility with the target editing software and publishing platform.

Key points for integrating TTS API

After enabling the TTS API on the dashboard, developers obtain the necessary credentials; they then select the appropriate model, speaker, as well as text and audio parameters according to the documentation provided. The billing is based on the number of characters processed, and the interface allows users to view the number of calls made, the total character count, the distribution of speakers, and historical trends.

API keys should be stored only on the server side, with limits set on usage, concurrency control, and retry mechanisms for exceptions.

The same fixed script can be used to cache the generated results, thereby avoiding repeated payments; a large number of short texts can be reasonably combined in accordance with the limitations set by the interface.

When the API usage reaches its limit, it may be temporarily restricted; it is necessary to settle the bill or contact support to increase the limit.

Web subscription credits cannot be used directly as API token balance.

The difference between open-source projects and platforms

The Dubverse commercial video localization platform is not an open-source product. However, the official GitHub repository publishes projects such as MahaTTS, MahaTTS v2, the voice data directory, and API documentation.

The first version of MahaTTS is released under the Apache 2.0 license and provides model options; however, it does not include the full set of functions for transcription, translation, subtitling, editing, hosting, and enterprise workflows available in the Dubverse web interface.

The code and terms of use for MahaTTS v2 must be checked against the current files in the repository; it cannot be assumed that the weights and data can be used for commercial purposes without restrictions just because it is labeled as open-source. For self-deployment, a GPU, the necessary environment, model security measures, and sound licensing are required.

Which users are it suitable for

• Creators who translate YouTube content, courses, and short videos into multiple languages;
• A team responsible for creating advertisements for international markets, product demonstrations, and social media videos;
• Filmmakers who need automatic subtitles, subtitle translation, and export in multiple formats;
• Companies that manage large-scale training, media, or educational content;
• Developers who generate speech in products using the character-based billing API.

Advantages and precautions

• The advantage of Dubverse is that it integrates transcription, translation, dubbing, subtitling, and studio editing into a single process, while using credits to clearly distinguish between these three types of tasks; it is suitable for content in Indian languages as well as in various international languages.
• Pro, Supreme, and Enterprise meet the needs of individuals as well as organizations, with a separate TTS API available;
• The limitations include high consumption of resources per minute for full voiceovers, advanced features being subject to package constraints, and errors possibly occurring in AI translation, speaker recognition, pronunciation, and lip synchronization.
• Videos, scripts, audio, music, character portraits, and translations may all be subject to intellectual property rights; prior authorization must be obtained, the facts must be verified, and synthetic content must be disclosed in accordance with applicable rules before it is made public.
