The term Diarization was initially associated with the task of detecting and segmenting homogeneous audio regions based on speaker identity. This task, widely known as speaker diariza-tion (SD), generates the answer for “who spoke when”. In the past few years, the term diarization has also been used in lin-guistic context.As per the definition of the task, the system hypothesis diarization output does not need to identify the speakers by name or definite ID, therefore the ID tags assigned to the speakers in both the hypothesis and the reference segmentation do not need to be the same.Enable Feature. To enable Diarization, use the following parameter in the query string when you call Deepgram’s /listen endpoint : To transcribe audio from a file on your computer, run the following cURL command in a terminal or your favorite API client. Replace YOUR_DEEPGRAM_API_KEY with your Deepgram API Key. AHC is a clustering method that has been constantly em-ployed in many speaker diarization systems with a number of di erent distance metric such as BIC [110, 129], KL [115] and PLDA [84, 90, 130]. AHC is an iterative process of merging the existing clusters until the clustering process meets a crite-rion. With speaker diarization, you can distinguish between different speakers in your transcription output. Amazon Transcribe can differentiate between a maximum of 10 unique speakers and labels the text from each unique speaker with a unique value (spk_0 through spk_9).In addition to the standard transcript sections (transcripts and items), requests …Speaker diarization: This is another beneficial feature of Azure AI Speech that identifies individual speakers in an audio file and labels their speech segments. This feature allows customers to distinguish between speakers, accurately transcribe their words, and create a more organized and structured transcription of audio files. To get the final transcription, we’ll align the timestamps from the diarization model with those from the Whisper model. The diarization model predicted the first speaker to end at 14.5 seconds, and the second speaker to start at 15.4s, whereas Whisper predicted segment boundaries at 13.88, 15.48 and 19.44 seconds respectively. Speaker Diarization is the task of segmenting audio recordings by speaker labels. A diarization system consists of Voice Activity Detection (VAD) model to get the time stamps of audio where speech is being spoken ignoring the background and Speaker Embeddings model to get speaker embeddings on segments that were previously time stamped. Speaker diarization is a task to label audio or video recordings with classes that correspond to speaker identity, or in short, a task to identify “who spoke when”. In the early years, speaker diarization algorithms were developed for speech recognition on multispeaker audio recordings to enable speaker adaptive processing. Abstract.
