FAQ

Common

Face API

  • What is Face Storage? What can it be used for?

    Face Storage allows a subscription to store additional persisted faces when using person objects and face lists for identification, or for similarity matching with the Face API.

  • How are the number of stored faces calculated for billing if it varies throughout the month?

    Stored images are charged at ¥1.59 per 1,000 faces. This rate is prorated on a daily basis. For example, if your account used 10,000 persisted faces each day for the first half of the month and none during the second half, you would only be billed for the number of days the 10,000 faces were stored for. This would be calculated as (¥1.59/1,000) x (10,000 x 15 + 0 x 16)/31 = ¥7.69. Alternatively, if you retained 1,000 faces for a few hours each day during a month and then deleted them every night, you would still be billed for the 1,000 persisted faces each day.

  • What is the capacity of Face Storage?

    The quota for stored person groups is currently 1,000. Each person group or FaceList can have a maximum of 1,000 people.

Computer Vision API

  • What operations can be completed with Computer Vision API?

    Tag - The Computer Vision API returns tags based on more than 2,000 recognizable objects, living beings, types of scenery, and actions. If tags are ambiguous or unusual, the API response will provide 'hints' to clarify the meaning of the tag.

    Face - Detects human faces within a picture.

    GetThumbnail - GetThumbnail generates high quality thumbnails after images are uploaded. The Computer Vision API algorithm analyzes objects within images, then crops images according to the requirements for the region of interest (ROI).

    Color - The Computer Vision algorithm extracts colors from an image. The colors are analyzed in three different contexts (foreground, background, and whole). They are grouped into 12 dominant accent colors.

    Image Type - The Computer Vision API can set a Boolean flag to indicate whether an image is black and white or color. It can use the same method to indicate whether an image is a line drawing. It can also indicate whether an image is clip art, along with its quality.

    OCR - Optical Character Recognition (OCR) technology detects text content in an image and extracts the identified text into a machine-readable character stream. You can use the results for searches and numerous other purposes, from medical records to security and banking. It automatically detects the language. OCR saves time and provides convenience for users by allowing them to simply take photos of text instead of transcribing it. Please refer to the Computer Vision Documentation page for supported languages.

    Adult - Apply adult/racy settings to automatically restrict adult content in images.

    Celebrities - Azure’s celebrity recognition model can recognize 200,000 celebrities from business, politics, sports, and entertainment around the world.

Content Moderator API

Text Analytics API

  • How does billing for the Text Analytics API work?

    The Text Analytics API can be purchased in units of the S0-S4 tier at a fixed price. Each unit of a tier comes with included quantities of API transactions. If the user exceeds the included quantities, overages are charged at the rate specified in the pricing table above. These overages are prorated and the service is billed on a monthly basis. The included quantities in a tier are reset each month. In the S tier, the service is billed for only the amount of Text Records submitted to the service.

  • What happens if I exceed the transaction limit on my free tier for Text Analytics?

    Usage is throttled if the transaction limit is reached on the Free tier. Customers cannot accrue overages on the free tier.

  • What constitutes a transaction in the S0-S4 tiers of the Text Analytics API?

    Any annotation to a document counts as a transaction. Batch scoring calls will also take into consideration the number of documents that need to be scored in that transaction. So for instance, if 1,000 documents are sent for sentiment analysis in a single API call, that will count for 1,000 transactions. If an API supports more than one annotation operation, that will also be considered. Let’s say an API call performs both sentiment analysis and key-phrase extraction on 1,000 documents, that will count for 2,000 transactions (2 annotations × 1,000 documents).

  • What happens if I exceed the transaction limit on the S0-S4 tier?

    If the usage on the S0-S4 tier is exceeded, the account starts to accrue overages. These overages are billed on a monthly basis and are calculated at the rate specified for each tier.

  • Can I change the tier of service I subscribed to?

    You may upgrade to a higher tier at any time. Billing rate and included quantities corresponding to the higher tier will begin immediately.

  • What constitutes a Text Record in the S Tier?

    A text record in the S tier contains up to 1,000 characters as measured by String.Length. If an input document into the text analytics API is more than 1,000 characters, it counts as one text record for each unit of 1,000 characters. For instance, if an input document sent to the API contains 7,500 characters, it would count as 8 text records. If an input document sent to the API contains 500 characters, it would count as 1 text record. If two documents are submitted, one document of 500 characters and one document of 1,200 characters, then the service would be billed for three text records in total: one record for the 500 character document and two text records for the 1,200 character document.

Translator Text API

  • How do I calculate monthly volume?

    For the Microsoft Translator Text API, the volume you are billed for is the number of characters in the input. Every Unicode code point counts as a character. Every character of the input counts. Each translation of a text to a new language counts as a separate translation. The number of queries, words, bytes, or sentences is irrelevant.

    To estimate your monthly volume, take the total characters to translate, multiply it by the number of languages you want to have it translated into, then take the number and spread it over the maximum number of hours or days you are able to wait for completion.

    More information on how we count characters for the Translator Text API can be found in our documentation.

  • What happens if I reach the limit of the free subscription plan?

    If you subscribe to the free subscription plan, the Microsoft Translator service will stop if you reach 2 million characters during a subscription month for the Text Translation API. The Microsoft Translator service will start again at the beginning of your next subscription month or when you change your subscription to a paid plan.

  • What languages does Microsoft Translator support?

    See the language list for text translation using the Microsoft Translator Text API.

    Developer oriented language lists, including language codes can be found in our documentation.

  • Can I customize my translations?

    Customization currently is not available with subscriptions on Azure.cn.

Language Understanding API

  • What is a transaction?

    For text requests, a transaction is an API call with query length up to 500 characters.

    For speech requests, a transaction is an utterance with query length up to 15 seconds long.

  • Is speech requests included in the free tier?

    No, the free tier only includes text requests with max length 500 characters.

  • What is a Dispatch?

    Dispatch is a feature that enables processing two models/applications with one API call.
