 ## Real-time speech to text
 
 Real-time speech to text transcribes audio as it's recognized from a microphone or file. It's ideal for applications requiring immediate transcription, such as: 
-- Transcriptions, captions, or subtitles for live meetings: Real-time audio transcription for accessibility and record-keeping. 
-- Diarization: Identifying and distinguishing between different speakers in the audio. 
-- Pronunciation assessment: Evaluating and providing feedback on pronunciation accuracy. 
-- Call center agents assist: Providing real-time transcription to assist customer service representatives. 
-- Dictation: Transcribing spoken words into written text for documentation purposes. 
-- Voice agents: Enabling interactive voice response systems to transcribe user queries and commands.

 Fast transcription API is used to transcribe audio files with returning results synchronously and faster than real-time audio. Use fast transcription in the scenarios that you need the transcript of an audio recording as quickly as possible with predictable latency, such as: 
 
-- Quick audio or video transcription and subtitles: Quickly get a transcription of an entire video or audio file in one go.
-- Video translation: Immediately get new subtitles for a video if you have audio in different languages.

 ## Batch transcription API
 
 [Batch transcription](batch-transcription.md) is designed for transcribing large amounts of audio stored in files. This method processes audio asynchronously and is suited for: 
-- Transcriptions, captions, or subtitles for prerecorded audio: Converting stored audio content into text. 
-- Contact center post-call analytics: Analyzing recorded calls to extract valuable insights.
-- Diarization: Differentiating between speakers in recorded audio.

 Out of the box, speech recognition utilizes a Universal Language Model as a base model that is trained with Microsoft-owned data and reflects commonly used spoken language. The base model is pretrained with dialects and phonetics representing various common domains. When you make a speech recognition request, the most recent base model for each [supported language](language-support.md?tabs=stt) is used by default. The base model works well in most speech recognition scenarios.
 
 Custom speech allows you to tailor the speech recognition model to better suit your application's specific needs. This can be particularly useful for: 
-- Improving recognition of domain-specific vocabulary: Train the model with text data relevant to your field. 
-- Enhancing accuracy for specific audio conditions: Use audio data with reference transcriptions to refine the model.
