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