Podcastle launches AI text to speech model: 450 voice options

In the rapidly growing podcasting field, the Podcastle platform recently announced the launch of its new AI text-to-speech model, Asyncflow v1.0. This new model not only provides users with more than 450 different AI voices, but also opens up API interfaces to developers so that they can integrate this text-to-speech feature directly into their own applications.

Podcastle founder Arto Yeritsyan said the company has always wanted to develop a text-to-speech model, but this desire has not been realized due to the high training costs and data requirements in the past. However, with the advancement of large-scale language model technology in recent years, Podcastle finally made a breakthrough last year, and was able to build high-quality voice models without requiring a large amount of data. Yeritsyan added that Podcastle's R&D was backed by a $13.5 million Series A round, which provides important guarantees for its technological innovation.

In terms of price, Podcastle's text-to-voice service is priced at about $40 per 500 minutes, compared to $99 for rival ElevenLabs. In addition to the text-to-speech model, Podcastle's voice cloning function has also been upgraded. The training process has been shortened from the previous one that required 70 different sentences to the recording that now takes only a few seconds. The new process leverages Podcastle’s Magic Dust AI technology launched last year, significantly improving the quality of audio recording.

In actual testing, although the newly generated voice sounds slightly robotic, it can still mimic the speaker's tone better. Podcastle says that over time, the feature will continue to improve, and users can also train different sound effects through different recording samples.

Yeritsyan notes that in addition to cost advantages, integrating audio, video, podcasting and AI-powered narrative tools into a redesigned website will also set Podcastle apart from the competition. He mentioned that although most users still mainly use Podcastle for audio content creation, the demand for video production is also gradually increasing.
