Getting Started

Step 1: Create a Google Cloud Account

Start by creating a Google Cloud account. If you already have one, feel free to skip this step. For those who need to create a new account, you can sign up here.

Step 2: Create a New Project

In the top left corner, click on the project dropdown menu and select New Project. Name your project and click Create.

Step 3: Enable API

Navigate to Speech in the Google Cloud console and click ENABLE API.

Step 4: Create an STT Recognizer

In the left sidebar, click on Recognizers > CREATE RECOGNIZERS. Name your recognizer chirp-recognizer, select Chirp as the model, and choose the language en-US. Leave the rest of the settings as default and click Save.

Step 5: Create a New Workspace

Go to the Workspace dropdown menu and select New Workspace. A sidebar will pop up on the right side of your screen.

Select Browse > Create a new bucket. Name your bucket chirp-bucket and click Continue. You can leave the rest of the bucket settings as default.

Click Create, and you should see a new bucket created successfully.

Finally, click on Select > Continue > Create to complete the workspace setup for the speech-to-text user interface.

Step 6: Create a New Transcription

To perform actual transcription, navigate to Transcription > New Transcription. Select your audio file either through Local upload or Cloud storage. For this tutorial, we will use the Local upload option.

Once you've selected your audio file, click Continue.

Change the default API version from V1 to V2. Specify the spoken language as English (United States) - en-US, choose Chirp as the transcription model, and select your newly created chirp-recognizer as the recognizer.

Click Submit and wait for a few moments as the transcription is processed.

Step 7: View Transcription Results and Download

To view the transcription results, simply click on the name of your transcription in the dashboard. You also have the option to download the results in four different formats: JSON, TXT, SRT, and CSV.

For instance, to download the transcription in TXT format, click Download > TXT > Download.
