Enhancing Whisper transcriptions: pre- & post-processing techniques
This notebook offers a guide to improve the Whisper's transcriptions. We'll streamline your audio data via trimming and segmentation, enhancing Whisper's transcription quality. After transcriptions, we'll refine the output by adding punctuation, adjusting product terminology (e.g., 'five two nine' to '529'), and mitigating Unicode issues. These strategies will help improve the clarity of your transcriptions, but remember, customization based on your unique use-case may be beneficial.
Installation
Install the Azure OpenAI SDK using the below command.

Setup
To get started let's import a few different libraries:
-
Naudio is a simple and easy-to-use library for audio processing tasks such as slicing, concatenating, and exporting audio files.
-
For our audio file, we'll use a fictional earnings call written by ChatGPT and read aloud by the author.This audio file is relatively short, but hopefully provides you with an illustrative idea of how these pre and post processing steps can be applied to any audio file.
[8]
[9]
At times, files with long silences at the beginning can cause Whisper to transcribe the audio incorrectly. We'll use `NAudio`` to detect and trim the silence.
[10]
[11]
Here, we've set the decibel threshold of -19. You can change this if you would like.
[12]
Now that we have audio segments we can create trimmed files to use with the Whisper model.

Good afternoon, everyone, and welcome to FinTech Plus Sync's second quarter 2023 earnings call. I'm John Doe, CEO of FinTech Plus. We've had a stellar Q2 with a revenue of $125 million, a 25% increase year-over-year. Our gross profit margin stands at a solid 58%, due in part to cost efficiencies gained from our scalable business model. Our EBITDA has surged to $37.5 million, translating to a remarkable 30% EBITDA margin. Our net income for the quarter rose to $16 million, which is a noteworthy increase from $10 million in Q2 2022. Our total addressable market has grown substantially, thanks to the expansion of our high-yield savings product line and the new RoboAdvisor platform. We've been diversifying our asset-backed securities portfolio, investing heavily in collateralized debt obligations and residential mortgage-backed securities. We've also invested $25 million in AAA-rated corporate bonds, enhancing our risk-adjusted returns. As for our balance sheet, total assets reached $1.5 billion, with total liabilities at $900 million, leaving us with a solid equity base of $600 million. Our debt-to-equity ratio stands at 1.5, a healthy figure considering our expansionary phase. We continue to see substantial organic user growth, with customer acquisition costs dropping by 15% and lifetime value growing by 25%. Our LTVCAC ratio is at an impressive 3.5%. In terms of risk management, we have a value-at-risk model in place, with a 99% confidence level indicating that our maximum loss will not exceed $5 million in the next trading day. We've adopted a conservative approach to managing our leverage, and have a healthy Tier 1 capital ratio of 12.5%. Our forecast for the coming quarter is positive. We expect revenue to be around $135 million, an 8% quarter-over-quarter growth, driven primarily by our cutting-edge blockchain solutions and AI-driven predictive analytics. We're also excited about the upcoming IPO of our fintech subsidiary, Pay Plus, which we expect to raise $200 million, significantly bolstering our liquidity and paving the way for aggressive growth strategies. We thank our shareholders for their continued faith in us, and we look forward to an even more successful Q3. Thank you so much.
This function will add formatting and punctuation to our transcript. Whisper generates a transcript with punctuation but without formatting.
