How AWS Transcribe works:
AWS Transcribe is a fully managed, automatic speech recognition (ASR) service that makes it easy to add speech-to-text capabilities to your applications. Here’s how it works:
You can upload audio files in various formats, including MP3, MP4, WAV, FLAC, and others. You can also stream audio in real-time using Amazon Kinesis Video Streams.
Automatic Speech Recognition:
Once the audio input is received, AWS Transcribe automatically transcribes the speech to text using advanced deep learning techniques. It recognizes individual words and punctuation and converts the spoken words into written text.
AWS Transcribe also allows you to create custom vocabularies to improve transcription accuracy for specific words or phrases that are unique to your domain. This is particularly useful for technical terms, industry-specific jargon, or product names that might not be recognized by the built-in language models.
Speaker and Channel Identification:
AWS Transcribe can identify different speakers in a conversation and label them accordingly. It can also identify different audio channels in a file and transcribe each one separately, making it useful for transcribing multi-speaker recordings or conference calls.
AWS Transcribe supports a variety of output formats, including JSON, plain text, and subtitle formats (SRT and VTT). This makes it easy to integrate the transcribed text into your applications or workflows. You can also configure the level of detail included in the output, such as timestamps, confidence scores, and punctuation.
