Devs seek local Whisper alternatives for bilingual STT

Whisper is no longer the undisputed default for local STT as developers hit its latency and language-specific accuracy walls.

• –Specialized open-source models like Kotoba-Whisper and ReazonSpeech are now significantly outperforming Whisper for Japanese transcription
• –Strict VRAM limits on consumer GPUs are driving the adoption of distilled variants and efficient inference frameworks like Sherpa-ONNX
• –Real-time pipeline requirements are pushing the community away from Whisper's chunk-based processing toward streaming-first architectures
