Pricing
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.

Dimensions summary
You have two ways to buy Lightning ASR real-time speech recognition. The ASR Audio Minutes option charges you per minute of audio you transcribe through the API. Your cost scales directly with how much audio you process, so you pay only for what you use. The Business Plan option bundles up to 399,800 minutes into a single commitment. Choose per-minute billing for variable or lower-volume usage, or the Business Plan when you can forecast higher transcription volume and prefer a set included allotment.
Top-of-mind questions for buyers
One unit is one minute of audio you send through the Lightning ASR API for transcription. The API supports both live streaming and pre-recorded audio. You are charged based on the length of audio processed, not the number of requests or words returned.
The Business Plan includes up to 399,800 minutes as its set allotment. The listing does not specify overage behavior once you pass that included amount. For details on how usage beyond the plan allotment is handled, contact the vendor before committing.
The ASR Audio Minutes option meters each minute you transcribe, so your cost rises and falls with usage. The Business Plan bundles a set allotment of up to 399,800 minutes into one commitment. Per-minute suits variable or lower volume; the Business Plan suits predictable, higher volume.
