you will get following error if administrator permission is not there:

GPU execution needs CUDA 11.
GPU execution requires the following NVIDIA libraries to be installed:
There are multiple ways to install these libraries. The recommended way is described in the official NVIDIA documentation, but we also suggest other installation methods below.
on google colab run this to install CUDA dependencies:
!apt install libcublas11
You can see this example notebook
pip install speechlib
This library does speaker diarization, speaker recognition, and transcription on a single wav file to provide a transcript with actual speaker names. This library will also return an array containing result information. ⚙
This library contains following audio preprocessing functions:
-
convert other audio formats to wav
-
convert stereo wav file to mono
-
re-encode the wav file to have 16-bit PCM encoding
Transcriptor method takes 7 arguments.
-
file to transcribe
-
log_folder to store transcription
-
language used for transcribing (language code is used)
-
model size ("tiny", "small", "medium", "large", "large-v1", "large-v2", "large-v3")
-
ACCESS_TOKEN: huggingface acccess token (also get permission to access
pyannote/[email protected]) -
voices_folder (contains speaker voice samples for speaker recognition)
-
quantization: this determine whether to use int8 quantization or not. Quantization may speed up the process but lower the accuracy.
voices_folder should contain subfolders named with speaker names. Each subfolder belongs to a speaker and it can contain many voice samples. This will be used for speaker recognition to identify the speaker.
if voices_folder is not provided then speaker tags will be arbitrary.
log_folder is to store the final transcript as a text file.
transcript will also indicate the timeframe in seconds where each speaker speaks.
from speechlib import Transcriptor
file = "obama_zach.wav" # your audio file
voices_folder = "voices" # voices folder containing voice samples for recognition
language = "en" # language code
log_folder = "logs" # log folder for storing transcripts
modelSize = "tiny" # size of model to be used [tiny, small, medium, large-v1, large-v2, large-v3]
quantization = False # setting this 'True' may speed up the process but lower the accuracy
ACCESS_TOKEN = "your huggingface access token" # get permission to access pyannote/[email protected] on huggingface
# quantization only works on faster-whisper
transcriptor = Transcriptor(file, log_folder, language, modelSize, ACCESS_TOKEN, voices_folder, quantization)
# use normal whisper
res = transcriptor.whisper()
# use faster-whisper (simply faster)
res = transcriptor.faster_whisper()
res --> [["start", "end", "text", "speaker"], ["start", "end", "text", "speaker"]...]
start: starting time of speech in seconds
end: ending time of speech in seconds
text: transcribed text for speech during start and end
speaker: speaker of the text

These metrics are from Google Colab tests.
These metrics do not take into account model download times.
These metrics are done without quantization enabled.
(quantization will make this even faster)
metrics for faster-whisper "tiny" model:
on gpu:
audio name: obama_zach.wav
duration: 6 min 36 s
diarization time: 24s
speaker recognition time: 10s
transcription time: 64s
metrics for faster-whisper "small" model:
on gpu:
audio name: obama_zach.wav
duration: 6 min 36 s
diarization time: 24s
speaker recognition time: 10s
transcription time: 95s
metrics for faster-whisper "medium" model:
on gpu:
audio name: obama_zach.wav
duration: 6 min 36 s
diarization time: 24s
speaker recognition time: 10s
transcription time: 193s
metrics for faster-whisper "large" model:
on gpu:
audio name: obama_zach.wav
duration: 6 min 36 s
diarization time: 24s
speaker recognition time: 10s
transcription time: 343s
because older versions give more accurate transcriptions. this was tested.
