# gather

The `gather` command is used to collect dtmf or speech input.

```json
{
  "verb": "gather",
  "actionHook": "http://example.com/collect",
  "input": ["digits", "speech"],
  "bargein": true,
  "dtmfBargein": true,
  "finishOnKey": "#",
  "numDigits": 5,
  "timeout": 8,
  "recognizer": {
    "vendor": "Google",
    "language": "en-US",
    "hints": ["sales", "support"],
    "hintsBoost": 10
  },
  "say": {
    "text": "To speak to Sales press 1 or say Sales.  To speak to customer support press 2 or say Support",
    "synthesizer": {
      "vendor": "Google",
      "language": "en-US"
    }
  }
}
```

You can use the following options in the `gather` command:

| option        | description | required  |
| ------------- |-------------| -----|
| actionHook | Webhook POST to invoke with the collected digits or speech. The payload will include a 'speech' or 'dtmf' property along with the standard attributes.  See below for more detail.| yes |
| bargein | allow speech bargein, i.e. kill audio playback if caller begins speaking | no |
| dtmfBargein | allow dtmf bargein, i.e. kill audio playback if caller enters dtmf | no |
| finishOnKey | Dmtf key that signals the end of input | no |
| input |Array, specifying allowed types of input: ['digits'], ['speech'], or ['digits', 'speech'].  Default: ['digits'] | no |
| interDigitTimeout | Amount of time to wait between digits after minDigits have been entered.| no |
|listenDuringPrompt| if false, do not listen for user speech until say or play has completed.  Defaults to true|no|
| minBargeinWordCount | if bargein is true, only kill speech when this many words are spoken.  Defaults to 1 | no|
| minDigits | Minimum number of dtmf digits expected to gather.  Defaults to 1. | no |
| maxDigits | Maximum number of dtmf digits expected to gather | no |
| numDigits | Exact number of dtmf digits expected to gather | no |
| partialResultHook | Webhook to send interim transcription results to. Partial transcriptions are only generated if this property is set. | no |
| play | nested [play](#play) Command that can be used to prompt the user | no |
| fillerNoise | play audio to the caller while the remote application is processing gather transcriptions. See [Using filler noise](/docs/supporting-articles/using-filler-noise) for more details.| no |
| fillerNoise.enable | boolean, whether to enable or disable filler noise | yes |
| fillerNoise.url | http(s) audio to play as filler noise | yes |
| fillerNoise.startDelaySecs | integer value specifying number of seconds to wait for a response from the remote | [recognizer](/docs/webhooks/recognizer) | Speech recognition options | no |

In the case of speech input, the actionHook payload will include a `speech` object with the response from Google speech:
```json
"speech": {
			"stability": 0,
			"is_final": true,
			"alternatives": [{
				"confidence": 0.858155,
				"transcript": "sales please"
			}]
		}
```

In the case of digits input, the payload will simple include a `digits` property indicating the dtmf keys pressed:
```json
"digits": "0276"
```

**Note**: an HTTP POST will be used for both the `action` and the `partialResultCallback` since the body may need to contain nested JSON objects for speech details.

Note: the `partialResultCallback` web callback should not return content; any returned content will be discarded.
