Voice assistant middleware

SDK and speech middleware for a large consumer voice platform — handling latency-sensitive audio paths and graceful recovery across flaky networks.

Java C++ Streaming audio Low-latency IPC

The problem. Voice assistants live or die on first-utterance latency. Every millisecond of middleware adds up — and the network will drop.

What we build. Middleware that streams audio with bounded memory, reconnects transparently, and keeps sessions alive across device handoffs.

Scope of past engagements

  • Low-latency SDKs running on millions of devices
  • Reconnection logic that survived real-world Wi-Fi behavior
  • Graceful degradation when downstream services slowed
This engagement is described in generic terms. Specific clients, metrics, and internal system names are intentionally withheld.
