llama.cpp 0.9.0 enhances local speech AI, but Windows audio latency persists

By PulseAugur Editorial · [1 sources] ·

The latest release of llama.cpp, version 0.9.0, introduces significant improvements for local speech processing, including Chatterbox TTS and Nemotron 3.5 Transcribe support. This update brings OCP FP8 E4M3 quantization for larger models and enhances the unified KV cache for better multi-sequence performance. While these advancements streamline local TTS and STT pipelines, the primary bottleneck for real-time applications on Windows remains the operating system's audio capture path, which introduces considerable latency.
