Talking-character: Example won't compile. Error

Hi, I'm excited to try this but can't get it to compile. Here the error I get after running npm start:

```
Failed to compile.

./src/apis/speechRecognition.ts 132:47
Module parse failed: Unexpected token (132:47)

| case 0:

| if (!base64Data) {
| _context2.next = 7;

```
I'm running this in VSCode on a M1 Macbook btw
