    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.
