You can get other models here
The one included in the build is ggml-base-q5_1.bin
From the OpenAI GitHub page, “The .en models for English-only applications tend to perform better… Additionally, the turbo model is an optimized version of large-v3 that offers faster transcription speed with a minimal degradation in accuracy.”
Models with “q5” are quantized and smaller and often faster. You can read more about that here.
Maybe enabling “Include non-spoken sounds” checkbox can improve timing.
