Error while trying to plot speaker similarity in Resemblyzer

[sankalpbhatia20]

Hey developers! I am new to Resemblyzer and it seems quite interesting.

I am using Resemblyzer to get the similarity chart for the speakers in an MP3 file that I have but I am getting an error. I even tried using the exact MP3 file given in the repository but I still got the same error.

The code:

from resemblyzer import preprocess_wav, VoiceEncoder
from demo_utils import *
from pathlib import Path

wav_fpath = Path("/Users/sankalpbhatia/Dropbox/Mac/Desktop/voice_similarity/meta_full_qa.mp3")
wav = preprocess_wav(wav_fpath)

# Cut some segments from single speakers as reference audio
segments = [[5, 10], [52, 59], [274, 284]]
speaker_names = ["David (Dave) Wehrner (CFO)", "Sheryl Sandberg (COO)", "Mark Zuckerberg (CEO)"]
speaker_wavs = [wav[int(s[0] * sampling_rate):int(s[1] * sampling_rate)] for s in segments]

encoder = VoiceEncoder("cpu")
print("Running the continuous embedding on cpu, this might take a while...")
_, cont_embeds, wav_splits = encoder.embed_utterance(wav, return_partials=True, rate=16)

speaker_embeds = [encoder.embed_utterance(speaker_wav) for speaker_wav in speaker_wavs]
similarity_dict = {name: cont_embeds @ speaker_embed for name, speaker_embed in 
                   zip(speaker_names, speaker_embeds)}

interactive_diarization(similarity_dict, wav, wav_splits)
