Comprehensive Detailed Explanation
The scenario:
You are working with Azure AI Video Indexer.
You need to add a custom brand/logo and also configure an exclusion so that this brand is not indexed.
In Video Indexer's REST API for brands, the configuration JSON includes:
" enabled " : true/false # Determines whether the brand should be indexed.
Setting " enabled " : false means the brand is excluded.
The other properties in the dropdown ( state , tags , useBuiltin ) are not correct in this context for configuring exclusions.
Therefore, to exclude a custom brand:
" enabled " : false
Attribute: " enabled "
Value: false

Scenario Recap
You are building a streaming Speech-to-Text solution using the Speech SDK.
Input audio format: MP3 encoding
You must configure the audio stream format and the recognizer properly.
Code Analysis
Audio Format
For MP3 streams, the correct method is:
AudioStreamFormat.GetCompressedFormat(AudioStreamContainerFormat.MP3)
This creates an audio format object for compressed MP3 input.
Recognizer
Since the task is speech-to-text transcription, you need the SpeechRecognizer class.
Other options like KeywordRecognizer, SpeakerRecognizer, or SpeechSynthesizer are not appropriate (they handle keyword spotting, speaker identification, or text-to-speech).
Completed Code Snippet
var audioFormat = AudioStreamFormat.GetCompressedFormat(AudioStreamContainerFormat.MP3); var speechConfig = SpeechConfig.FromSubscription( " 18c51a87-3a69-47a8-aedc-a54745f708a1 " , " westus
" );
var audioConfig = AudioConfig.FromStreamInput(pushStream, audioFormat); using ( var recognizer = new SpeechRecognizer(speechConfig, audioConfig))
{
var result = await recognizer.RecognizeOnceAsync();
var text = result.Text;
}
Final Answer (Answer Area Selections)
AudioFormat: AudioStreamFormat.GetCompressedFormat
Recognizer: SpeechRecognizer

Statements Analysis
The code will detect the language of documents.
The method used is RecognizeLinkedEntities .
This extracts linked entities and provides Wikipedia references but does not perform language detection.
For language detection, you must call DetectLanguage() .
The answer: No
The url attribute returned for each linked entity will be a Bing search link.
The RecognizeLinkedEntities API returns a Url property for each entity that points to the Wikipedia page of the entity.
It does not return Bing links.
The answer: No
The matches attribute returned for each linked entity will provide the location in a document where the entity is referenced.
The matches collection contains objects with offset and length properties, which indicate where in the text the entity appeared.
This is correct.
The answer: Yes
Verified Answer
The code will detect the language of documents # No
The url attribute returned for each linked entity will be a Bing search link # No The matches attribute returned for each linked entity will provide the location in a document where the entity is referenced # Yes Microsoft References Azure Text Analytics - Recognize linked entities Text Analytics .NET SDK: RecognizeLinkedEntities
