Infimade Call

Call infrastructure and real-time AI voice.

A technical project combining telephony, call management, and AI voice processing.

Archived. Retained as a technical project; it is not currently an active commercial offering.

Bringing call control and voice processing together.

Infimade Call brings inbound, outbound, and internal calls into a backend system with call management, recording, call detail records, and live status updates.

The project also includes an AI voice pipeline using speech recognition, voice activity detection, a language model, and speech synthesis, alongside bidirectional audio-stream control.

Engineering considerations

The work spans call lifecycle management, live application state, and continuous audio processing.

Call lifecycle

Keeping call state, recordings, and call records connected throughout a session.

Bidirectional audio

Handling both sides of a conversation while retaining control over audio flow.

Voice interaction

Coordinating speech detection, recognition, language-model responses, and synthesized audio within a live call.
