Increasing performance speed and Accuracy

Hi,

I have tested vosk api on cpu computer . It takes about 90 seconds to recognize a 60 seconds microphone . During processing it takes about 25% of CPU ( I think it runs only on one core).
i use intel cpu core i7 , 4.3 GHZ , os windows 64 bit

Is there any way to use more cores and speed up speech recognition onspeech to text ? The only way that I'm thinking about is overclocking. I was wondering if exists an environment variable for vosk or kaldi to define number of processing thread.
