Socket.IO
Socket.IO
In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured!

Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables low-latency, bidirectional and event-based communication between a client and a server. It is built on top of the WebSocket protocol and provides additional guarantees like a fallback to HTTP long-polling or automatic reconnection. WebSocket is a communication protocol that provides a full-duplex and low-latency channel between the server and the browser. There are several Socket.IO server implementations available. And client implementations in most major languages. -

Inworld Realtime STT
Inworld
Inworld Realtime STT is a realtime streaming STT API that understands users beyond their words. It combines low-latency speech recognition with voice profiling, extracting emotion, vocal style, accent, age, and pitch directly from raw audio so downstream LLMs and TTS systems can respond with more adaptive, expressive behavior. Developers can stream audio in real time, transcribe complete files, or extract voice profile signals through one unified API, with realtime bidirectional streaming over WebSocket, synchronous transcription for full audio files, voice profile signals on every streaming chunk, and multi-provider support through a single model ID. Every audio chunk can produce a realtime profile of the speaker with confidence scores, giving LLMs structured context such as whether a user sounds sad, frustrated, soft, high-pitched, or calm.Starting Price: Free -
