Voicegain Cloud -  Assumptions

1.   Platform usage is measured and billed per second but the invoices generated by our billing system report the usage in hours.

3.  Basic model offers STT on a mono-channel with no Diarization or PII redaction. Enhanced model offers STT for two-channel call center audio (Agent and Caller  on separate channels) It also includes Diarization (mono channel with multiple speakers) and PII Redaction.

4. STT Realtime-Basic and STT Realtime-Enhanced are for streaming audio over Web-socket. Basic is for mono channel with no diarization. Enhanced is for two-channel/stereo call center audio for call center application.

Voicegain Edge - Assumptions

1. Voicegain Edge refers to our platform being deployed on client's private infrastructure (Bare-metal in a datacenter or Private Cloud). Voicegain is deployed on a Kubernetes Cluster. We prefer NVIDIA GPUs for apps that require high concurrency. CPUs are supported for low concurrency apps.  Orchestration of the cluster is from Voicegain cloud.

2. Client shall incur infrastructure costs and is responsible for monitoring of Kubernetes. For Private Cloud, we recommend managed Kubernetes from the cloud provider. For Datacenter, please contact us for support options.
3.  "Port" - for STT Offline - is defined as throughput. So 25 Ports would allow you to transcribe 25 hours of offline audio per hour. For Real-time STT, Port is the number of concurrent web-socket sessions. E.g 25 Ports means a maximum of 25 Concurrent Real-time STT sessions during a month.

4.  For usage based licensing, each request is subject to a minimum billing of 6 seconds and 1 second increment after that. E.g. a real-time request for 4 seconds shall be billed for 6 seconds or $0.0012 ($0.00020*6) and a real-time request for 7 seconds shall be billed for 7 seconds.

5.  Voicegain offers discounts for volume & term commits. Please contact us at to receive custom pricing.
