Study Notes
Amazon Transcribe Overview
- Amazon Transcribe automatically converts speech to text using automatic speech recognition (ASR).
- Users input audio, and Transcribe outputs the transcribed text.
- Example: "Hey, hello, my name is Stephane and I hope you're enjoying the course!" is transcribed.
Features
- PII Redaction: Automatically removes personally identifiable information (PII) like names, addresses, and social security numbers.
- Multilingual Support: Handles multiple languages in a single audio file.
- Use Cases: Transcribing customer service calls, creating closed captions/subtitles, generating metadata for searchable media archives.
Improving Accuracy
- Custom Vocabularies: Allows adding specific words, phrases, and domain-specific terms to enhance recognition of uncommon or technical language.
- Pronunciation Hints: Providing hints on how to pronounce words and phrases can improve recognition accuracy.
- Example: Adding "AWS microservices" vocabulary to avoid misrecognition of similar sounding phrases such as "USA my crow services".
- Custom Language Models: Training the Transcribe model on domain-specific text data to provide context around words.
- Example: Training on IT-related texts to understand "microservice" context for IT professionals or training on bird-related text to provide context when the subject is birds
Toxicity Detection
- Automatic identification of toxic speech: Uses both audio (tone, pitch) and text cues (profanity, hate speech).
- Categorization: Classifies toxicity into categories like sexual harassment, hate speech, threats, abuse, and insults.
- Combined approach: Combining analysis of audio and text for better accuracy in identifying toxicity.
