I want to know when I will be charged for using the SpeechSDK.

Question

Hi. I am using SpeechSDK for Speech To Text and Text To Speech. I would like to know when I will be paid. SpeechToText payment is based on the length of the words when using SpeechSynthesizer.SpeakTextAsync. Text To Speech payment is based on the length of the sentence when you use SpeechSynthesizer.StartSpeakingTextAsync or SpeechSynthesizer.SpeakTextAsync Is this correct?

@魚井孝則 The usage of Azure speech services is based on the cumulative calls made to the resource for the respective API i.e text to speech or speech to text via REST API, SDK or speech studio. In your case, if you are using the SDK the call to synthesize text passes certain text or characters and these processed characters count is recorded for billing against the resource and you will be billed based on the number of characters processed as per your pricing tier. Please see the pricing page for pricing for each scenario.

For speech to text scenarios, the billing will be based on the amount of audio hours processed when speech is passed as input through the API.

In all scenarios, the pricing will be pro-rated based on the amount of usage i.e characters or speech audio for TTS or STT respectively. If you are using other features like speaker recognition or speech translation the billing will be based on the criteria defined for these features.

The billing cycle is tied to your subscriptions billing cycle i.e whenever you recieve an invoice for your subscription the billing for your speech resource should also be included. Usually, this is every 30 days from the time your subscription is created. Please see this page for more details about invoices.
