# Real-time Call Analytics output
<a name="tca-output-streaming"></a>

Real-time Call Analytics transcripts are displayed in a turn-by-turn format by segment. They include category events, issue detection, sentiment, and PII identification and redaction. Category events allow you to set real-time alerts; see [Creating real-time alerts for category matches](tca-start-stream.md#tca-create-alert-stream) for more information.

To increase accuracy and further customize your transcripts to your use case, such as including industry-specific terms, add [custom vocabularies](custom-vocabulary.md) or [custom language models](custom-language-models.md) to your Call Analytics request. To mask, remove, or tag words you don't want in your transcription results, such as profanity, add [vocabulary filtering](vocabulary-filtering.md).

The following sections show examples of JSON output for real-time Call Analytics transcriptions.

## Category events
<a name="tca-output-category-event-stream"></a>

Here's what a category match looks like in your transcription output. This example shows that the audio from the 19010 millisecond timestamp to the 22690 millisecond timestamp is a match to the 'network-complaint' category. In this case, the custom 'network-complaint' category required that the customer said "*network issues*" (exact word match).

```
"CategoryEvent": { 
    "MatchedCategories": [ 
        "network-complaint" 
    ],
    "MatchedDetails": { 
        "network issues" : { 
            "TimestampRanges": [    
                { 
                    "BeginOffsetMillis": 9299375,
                    "EndOffsetMillis": 7899375
                }
            ]
        }
    }
},
```

## Issue detection
<a name="tca-output-issue-detection-stream"></a>

Here's what an issue detection match looks like in your transcription output. This example shows that the text from character 26 to character 62 describes an issue.

```
"UtteranceEvent": {
    ...
    "Transcript": "Wang Xiulan I'm tired of the network issues my phone is having.",
    ...
    "IssuesDetected": [
        {
            "CharacterOffsets": {
                "BeginOffsetChar": 26,
                "EndOffsetChar": 62
            }
        }
    ]
},
```

## Sentiment
<a name="tca-output-sentiment-stream"></a>

Here's what sentiment analysis looks like in your transcription output.

```
"UtteranceEvent": {    
    ...
    "Sentiment": "NEGATIVE",
    "Items": [{
        ...
```

## PII identification
<a name="tca-output-pii-id-stream"></a>

Here's what PII identification looks like in your transcription output.

```
"Entities": [
    {
        "Content": "Wang Xiulan",
        "Category": "PII",
        "Type": "NAME",
        "BeginOffsetMillis": 7999375,
        "EndOffsetMillis": 199375,
        "Confidence": 0.9989
    }
],
```

## PII redaction
<a name="tca-output-pii-redact-stream"></a>

Here's what PII redaction looks like in your transcription output.

```
"Content": "[NAME]. Hi, [NAME]. I'm [NAME] Happy to be helping you today.",
"Redaction": {
    "RedactedTimestamps": [
        {
            "BeginOffsetMillis": 32670,
            "EndOffsetMillis": 33343
        }, 
        {
            "BeginOffsetMillis": 33518,
            "EndOffsetMillis": 33858
        }, 
        {
            "BeginOffsetMillis": 34068,
            "EndOffsetMillis": 34488
        }
    ]
},
```

## Language identification
<a name="tca-output-language-id-stream"></a>

Here's what Language identification looks like in your transcription output.

```
{
  "LanguageCode": "en-US",
  "LanguageIdentification": [
    {
      "Code": "en-US",
      "Score": 0.823
    },
    {
      "Code": "de-DE",
      "Score": 0.177
    }
