SpeechGPT
What is SpeechGPT?
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.
AudioStack
What is AudioStack?
AudioStack turns a creative brief or block of raw text into finished radio spots, ads, and long-form audio without booking a studio. The company rebranded from Aflorithmic; the old domain still redirects to audiostack.ai. You can work in a self-serve console or embed the production engine through an API that returns white-labeled, broadcast-ready files.
Where most text-to-speech tools hand you a voice clip, AudioStack runs the full chain: script generation, voice casting across providers like ElevenLabs and OpenAI, music and SFX mixing, duration targeting for 6-second or 30-minute specs, mastering, and automated QA for loudness and brand rules. A case study on the site cites 1,500 hyperlocal ads produced in three days and a catalog of 2,600+ voices across 17 providers.
Agencies, ad-tech platforms, radio publishers, and audiobook producers are the core buyers. Products split between InstantCreative and DynamicCreative for self-serve campaign work and CreativeEngine and StoryEngine for API embedding inside other platforms.
