Show HN: Audio-chat-box – offline speech in and out for any program, over stdio (github.com)

Audio-chat-box, a new tool for enabling offline speech recognition and synthesis, has been unveiled, allowing developers to integrate voice interaction into their AI projects without reliance on the internet. This program works by reading text aloud using the Kokoro voice engine and converting speech to text with the Parakeet TDT model. It captures audio from the client’s microphone and processes it locally through the Silero Voice Activity Detector (VAD), ensuring that all data remains on the user's machine. Notably, it interacts with any software via standard input/output, using a straightforward JSON message protocol. This innovation is significant for the AI/ML community as it addresses privacy concerns and enhances accessibility by enabling hands-free operation of applications. The audio-chat-box is built for the Linux amd64 architecture and features a Docker demo that requires no API keys or internet connection, making it easy to deploy. Furthermore, it is designed to favor specific "hotwords," which can be defined by developers to enhance recognition accuracy in specialized contexts, such as gaming or education. This local-first approach aligns with growing trends in privacy-conscious AI development, making it a compelling option for developers looking to create engaging voice-enabled applications.
