Cost breakdown

Four rates make a call minute: telephony, speech-to-text, the language model and speech output. The table splits your cost per minute, per call and per month, and the chart shows which component takes the largest share.

How it is calculated

billed minutes = calls × answer rate × average length
per minute     = telephony + speech-to-text + model + speech output
per call       = per minute × average length
per month      = per minute × billed minutes
