List of Google ASR models. Can be passed via the `ASRParameters.model` parameter.
NOTE: the **enhanced** models cost more than the standard rate.
Add the following line to your scenario code to use the enum:

```
require(Modules.ASR);
```

| ------------------------------ | ---------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|  `DEFAULT`                     | `ASRModel` | Best for audio that is not one of the specific audio models. For example, long-form audio. Ideally the audio is high-fidelity, recorded at a 16khz or greater sampling rate. |
|  `default_enhanced`            | `ASRModel` | **Default** model with more accurate recognition.                                                                                                                            |
|  `command_and_search`          | `ASRModel` | Best for short queries such as voice commands or voice search.                                                                                                               |
|  `command_and_search_enhanced` | `ASRModel` | **Command\_and\_search** model with more accurate recognition.                                                                                                               |
|  `phone_call`                  | `ASRModel` | Best for audio that originated from a phone call (typically recorded at a 8khz sampling rate).                                                                               |
|  `phone_call_enhanced`         | `ASRModel` | **Phone\_call** model with more accurate recognition.                                                                                                                        |
|  `video`                       | `ASRModel` | Best for audio that originated from video or includes multiple speakers. Ideally the audio is recorded at a 16khz or greater sampling rate.                                  |
|  `video_enhanced`              | `ASRModel` | **Video** model with more accurate recognition.                                                                                                                              |
