How Siri Works
Siri leverages machine learning and AI algorithms to understand and respond to user queries. The workflow involves voice input capture, speech-to-text conversion, natural language understanding, response generation, and text-to-speech output.
Mathematical Models and Algorithms
Siri utilizes a variety of machine learning models including:
- Hidden Markov Models (HMM) for speech recognition.
- Natural Language Processing (NLP) models like Transformers.
- Deep Learning neural networks for contextual understanding.
Example of Model Structure (HMM):
graph TD;
A[Speech Input] --> B[Feature Extraction];
B --> C[State Estimation];
C --> D[Probability Calculation];
D --> E[Word Sequence Prediction];
