AI Text to Speech

NOTE This feature requires a VEGAS Pro 365, VEGAS Pro Edit or VEGAS Pro Post 365 subscription. To use this feature, you must first log into your VEGAS Hub account (see the VEGAS Hub section for more details).

The Text-to-Speech feature in VEGAS Pro allows you to convert text in videos into speech and add it as an audio file. It provides an efficient way to transform large amounts of text into speech without the need to hire professional voice actors. With this feature, you can utilize AI technology to generate computer-generated voices in various languages and voice options. Additionally, it offers the convenience of translating your narrations into different languages using natural-sounding native voices. Moreover, the cloud-based functionality enables you to seamlessly access new voices and features without requiring a new software build.

Using SSML input mode

SSML (Speech Synthesis Markup Language) is a markup language designed specifically for controlling the output of text-to-speech (TTS) systems. It allows for detailed instructions to format and style the spoken language, such as emphasizing certain words, controlling pause length, or changing speech speed.

SSML provides a set of tags that can be embedded within the text to indicate how it should be pronounced or delivered. These tags provide control over various aspects of speech synthesis, including prosody, pronunciation, volume, and more.
