Sample Audio Preview Page Added

Added a sample audio preview page where you can preview OpenAI TTS voices in different languages.

We have released the long-requested sample audio page, where you can preview samples created with the OpenAI text-to-speech API all in one place.

OpenAI TTS offers 11 voices: Alloy / Ash / Ballad / Coral / Echo / Fable / Onyx / Nova / Sage / Shimmer / Verse

To answer the common question "Which voice should I choose?", we have organized the samples by language so you can compare all 11 voices. Please use the page for narration tone selection and for checking language-specific nuances. Once you find a voice you like, you can select it directly from the voice settings when creating your video. For the basic workflow from upload to video creation, please see our How to Use page.

We will continue to expand the supported languages and samples. We look forward to your feedback and suggestions.
