How is speaker embedding used in voice recognition for transcripts?
AssemblyAI has detailed how speaker embedding technology is crucial for accurate voice recognition in transcriptions. This technology creates a unique numerical 'fingerprint' for each voice, capturing distinct vocal characteristics beyond basic pitch. Modern systems utilize neural network-based d-vectors for these embeddings, which are more effective than older i-vector methods, especially in noisy or short-utterance scenarios. The process involves segmenting audio into utterances, generating embeddings, clustering similar embeddings to identify speakers, and finally labeling the transcript. AI
