📊Create language evaluation for Speech Recognition

Set up a simple workflow to compare ASR models and evaluate the right choice for your product

Why do you need a Bulk and Evaluation Workflow?

When testing ASR models, your main goal is to scope out which model is best suited for your project needs.

There are several components to test:

• understanding model proficiency in global languages and local accents

• assessing the accuracy of translations

• checking for low Word Error Rate

• latency

• price

Features of Bulk Runner and Evaluation Workflow

1. Run several models in one click

2. Choose any of the API Response Outputs to populate your test

3. Built-in evaluation tool for quick analysis

4. Use csv or Google Sheets as input

5. Get output in CSV for further data analysis

Getting Started

Step 0 - Prepare your data

1. Collect all your audio voice samples into a Google Drive folder (make sure they are in .wav or .mp3 format)

2. In a new Google spreadsheet or CSV file copy the links of all your audio files

3. Add the human-created transcription for each sample

4. Add the English translation for each sample

Step 1 - Select the ASR Models

Head to our bulk and eval workflow.

In the example, we have already pre-filled the various models that can be tested. You can choose the ones you want to run by selecting it in the dropdown.

Select the models you want to evaluate your audio samples on

Step 2 - Add your CSV/Google Sheets

Upload your CSV/Google Sheet from Step 0. In this example, we have used a Google Sheet of 10 Audio Samples with transcripts and translations. A preview of your sheet will appear once it is correctly uploaded.

Step 3 - Select the input column

Select the column in the input from the dropdown box. The outputs will appear as various columns. In this example, it will be the "audios" column

Step 4 - Select the pre-built evaluator

In the "Evaluation Workflows" section select the "Speech Recognition Model Evaluator".

Step 5 - Hit Submit

Once you hit submit, the selected ASR model workflows (see Step 1) will run for each audio file in the sheet (see Step 2). An output CSV will be generated on the right-hand side of the page.

The outputs will appear in a table format on the right of the page, the output will appear in new columns after your originally populated columns

After the runs are complete, the selected Evaluator (see Step 4), will compare the ASR model outputs to the human-generated translations. It will assess and rate how accurately each model has translated the audio sample.

A bar graph with the performance will appear once the entire evaluation is complete.

After the evaluation is complete, table and a bar graph will show the evalution scores
