# What hardware do is needed for automated speech recognition (ASR) system?

### The following data was prepared for the year 2020.

:heavy\_check\_mark: Note that 1 vCPU can serve 4 concurrent ASR sessions over time.

:heavy\_check\_mark: RAM and HDD depend on the configuration of the virtual machines.

:heavy\_check\_mark: To calculate how many gigabytes are required for 1 server instance supporting N channels, you need to multiply the number of channels by 100 MB on top of obligatory the 4.5 GB.

 $$(4.5 GB + N \* 100 MB)$$

:heavy\_check\_mark: Each additional context model additionally requires at least 3GB RAM per 1 server instance.
