What is speechgpt?

SpeechGPT is a free, open-source web app that lets you have spoken conversations with ChatGPT. Instead of typing out messages, you talk to it, and it talks back. The main appeal is turning text-based AI chat into something closer to a real conversation, whether you want to practice speaking a foreign language or just have a hands-free chat with an AI assistant. To get started, you provide your own OpenAI API key, which is what connects the app to ChatGPT's underlying intelligence. For the speech side, the app has built-in voice recognition so it can hear what you say, and built-in speech synthesis so it can read responses out loud. If you want higher-quality voices, you can optionally connect it to paid services like Amazon Polly or Azure Speech Services by providing their access keys, but those add-ons are not required. The primary users are people who want to practice speaking another language without the pressure of talking to a real person, or anyone who finds voice interaction more natural than typing. Because it supports over 100 languages and is designed to work well on mobile phones, it is useful for language learners on the go. You could use it to rehearse conversational French, practice for a job interview, or just ask questions out loud while cooking. A notable design choice is the project's privacy approach: all your data stays stored locally on your device rather than being sent to a central server. This means your conversation history does not leave your phone or computer. For developers, the project also includes straightforward deployment options through platforms like Vercel or container tools like Docker, making it easy to host your own personal instance.
