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

The following data was prepared for the year 2020.

✔️ Note that 1 vCPU can serve 4 concurrent ASR sessions over time.

✔️ RAM and HDD depend on the configuration of the virtual machines.

✔️ 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.

$(4.5 GB + N * 100 MB)$

✔️ Each additional context model additionally requires at least 3GB RAM per 1 server instance.

	10 channels	50 channels	100 channels	200 channels
Virtual Machines	1	1	2	4
CPU Threads	3vCPU	12 vCPU	2x12 = 24 vCPU	4x12 = 48 vCPU
CPU points	2000 CPU	2000 - 2300CPU	2000 - 2300CPU	Min 2300CPU
Recommended Hardware	Xeon Gold 6136 or better	Xeon Gold 6136 or better	Xeon Gold 6136 or better	2 x Xeon Gold 6136 or better
Basic RAM	8 GB	16 GB	2 x 16 GB = 32 GB	4 x 16 GB = 64 GB
RAM in case u use up to 2 context models	16GB	24GB	2 x 24 GB = 48GB	4 x 24 GB = 96 GB recommended 128 GB
HDD	40 GB	60 GB	2 x 60 GB = 120 GB	4 x 60 GB = 240 GB
