SpeechGPT vs AudioStrip

SpeechGPT lets you hold voice conversations in the browser using your own OpenAI API key. You type or record messages, send them through a chat interface, and hear spoken replies without installing desktop software.

Unlike hosted TTS services that bundle model costs into a subscription, SpeechGPT runs in the browser and bills you only through the OpenAI, Azure Speech Services, or Amazon Polly accounts you connect. That makes it a lightweight option for developers and language learners who already have API access and want a simple voice chat front end.

The interface supports English, Spanish, and Chinese UI labels, includes a record button for speech input, and stores session data locally in the browser. It suits developers testing voice chat flows, language learners practicing spoken prompts, and anyone who wants a minimal ChatGPT voice client on mobile or desktop.

Upload a song to AudioStrip and download isolated vocals, drums, bass, and other stems for remixing, karaoke prep, or post-production work. Pick a separation model on the isolate page, wait for processing, and grab MP3 output on the free tier or WAV and FLAC on Premium. The same account also handles speech denoising, AI mastering, and key/BPM detection.

Where desktop stem splitters like Ultimate Vocal Remover expect local installs and GPU tuning, AudioStrip keeps everything in the browser with a generous free tier. The trade-off is queue time: free jobs can take 15 to 60 minutes, while Premium promises over 10x faster processing. AudioStrip Batch is a separate downloadable app that runs Demucs locally for folder-wide jobs, but only for paying subscribers on Windows or Mac.

The tool fits bedroom producers, karaoke app developers, and podcast editors who need quick stem splits without configuring Python environments. Queen Mary University and Innovate UK partnerships back the separation research, and testimonials on the homepage come from KaraFun Group and Royal Television Society composer Paul Farrer.
