Rask: A HeyGen alternative for video translation

HeyGen launched with a bang thanks to its Product Hunt campaign and the viral video of messi speaking english. But the tool still has its limitation. Their AI Video Translation with lip-sync is still in beta and their processing capacity is still limited.

So, for anyone trying to repurpose their content to reach a broader international audience Rask is our tool of choice. By uploading a video it matches voice tones and the quality is quite phenomenal. Also it allows to edit the SRT helping to fix common pronunciation errors or localized slang.

Differently to HeyGen's video translation, Rask works as an AI voiceover, so it doesn't try to do the magic of trying to look like Miley Cirus speaks French, but it works more like a dubbed telenovela. 

After the recent release of Spotify AI Translation, Rask comes handy for those who want to replicate it functionality for other content pieces, considering that users will start getting more used to consume content in their own language.

Their basic plan starts at $49 per month with 25 minutes of dubbing.

Voice Cloning with elevenlabs / 11labs / prime voice ai

One of the most exciting developments in AI-driven content creation is voice cloning. elevenlabs (formerly known as 11 labs or prime voice ai) has emerged as a leader in this field, offering creators the ability to clone their voices and apply them to translated content. This innovation ensures that the translated videos retain the unique vocal characteristics of the original creator, preserving their authenticity and connection with the audience. By using 11labs for voice training, content creators can generate voiceovers in multiple languages, allowing them to create content that feels personal and engaging, regardless of the viewer's native language.

Prime Voice AI lets you create high-quality spoken audio in any voice and style. The advanced AI model behind this tool is designed to reproduce human intonation and inflection with unprecedented accuracy, and to adapt delivery based on context. Whether you're a content creator, short story writer or video game developer, the possibilities for creating compelling audio are now endless.

For content creators, the company recently launched "ElevenLabs Dubbing Studios", the tool detects and labels each of your speakers and create an editable script of your content. In the editor, you can update translations, change the timing, and regenerate the dialogue until the accent and tone are just right.

Text-to-Speech in Multiple Languages

To further enhance the multilingual capabilities of their videos, content creators can rely on AI-powered text-to-speech (TTS) solutions. These TTS systems can convert written scripts into spoken language, ensuring that every word is pronounced accurately and naturally. This is particularly useful for content creators who might not have access to native speakers in all the languages they wish to target. With AI-driven TTS, creators can confidently deliver content in various languages while maintaining a high level of quality and fluency.

Wav2lip-2 API for Perfect Lipsync

Lipsyncing is a crucial element in creating professional-looking videos, and AI is making this process easier than ever before. The wav2lip-2 API, developed by @synchronicitylabs, is a state-of-the-art solution for achieving perfect lipsync in videos. This API leverages a cutting-edge model to match the movements of the lips with the translated audio seamlessly. The result is a high-definition video that appears as if the speaker is speaking fluently in the target language. This technology is a game-changer for content creators, as it eliminates the need for time-consuming manual lipsyncing and ensures a polished final product.

For those less experience with API devepment, looking for a consumer-facing solution, HeyGen is a great alterantive
