GPT4Audio

GPT4Audio is a Windows desktop application from Gravity Storm Software that converts spoken audio into text and translates audio files between languages, using OpenAI's Whisper technology under the hood. It supports live dictation into the app as well as processing of existing audio recordings, aimed at turning speech into usable written content in real time rather than after manual transcription. The product is part of a wider toolset from the same company that also includes Word Express, a Microsoft Word add-in launched in March 2023 that brings GPT, DALL-E 2, and Whisper capabilities directly into Word for generating text, images, and transcribed audio content inside documents. Together, the two products are positioned for people who write frequently, such as marketers, copywriters, and content creators, who want to dictate or translate material instead of typing it manually. Word Express is offered as an annual subscription billed at $15 per month, with free software updates included for subscribers; GPT4Audio itself has a separate purchase page on the company's site. One honest limitation: the company's main website returned a certificate error during this review, so some current details, such as exact GPT4Audio-specific pricing and any changes since launch, could not be independently re-verified beyond what is documented in third-party listings and the company's own product announcements found through search.
