Create custom language models tailored to users’ speaking styles
Don’t let varied vocabularies and speaking styles block understanding. Customize the language model of your app’s speech recognition by tailoring it to your industry expressions, technical, geography or market terms, and even speaker style.
Adapt to user environment with custom acoustic models
Make sure your app’s speech recognition can function in all environments. With custom acoustic models, you can account for background noise and match your users’ expected environments.
Use robust speech models from Microsoft
Enable powerful, personalized speech recognition by building your own customized speech recognition models on top of Microsoft’s existing state-of-the-art models.
Explore a speech scenario
With Speech Services, it's easy to transcribe every call. Index the transcription for full-text search, or apply Text Analytics to detect sentiment, language, and key phrases for insights. If your call center recordings involve specialized terminology, such as product names or IT jargon, create a custom language model to teach Speech Services the vocabulary. A custom acoustic model helps Speech Services understand speakers even with background noise or poor phone connections.
