Transcribe: Pipe-separated languageCodes are failing to satisfy enum value set

Question

Getting a very strange issue starting a TranscriptionJob. I am using the AWS SDK for PHP.

I am transcribing audio files that contain both English and Hebrew.

```
$client->startTranscriptionJob([
  'LanguageCode'          => 'en-US|he-IL', 
  'Media' => [
    'MediaFileUri'        => 'xxx'
  ],
  'OutputBucketName'      => 'xxx',
  'OutputKey'             => 'xxx.json',
  'TranscriptionJobName'  =>'xxx-job'
]);
```

This returns the following error: `BadRequestException (client): 1 validation error detected: Value 'en-US|he-IL' at 'languageCode' failed to satisfy constraint: Member must satisfy enum value set: [en-IE, ar-AE, te-IN, zh-TW, en-US, ta-IN, en-AB, en-IN, zh-CN, ar-SA, en-ZA, gd-GB, th-TH, tr-TR, ru-RU, pt-PT, nl-NL, it-IT, id-ID, fr-FR, es-ES, de-DE, ga-IE, af-ZA, en-NZ, ko-KR, hi-IN, de-CH, vi-VN, cy-GB, ms-MY, he-IL, da-DK, en-AU, pt-BR, en-WL, fa-IR, sv-SE, ja-JP, es-US, fr-CA, en-GB]`

**NOTE!!**: If I replace `LanguageCode` with `'en-US'` (or with `'he-IL'`), it works great... (*except of course for the fact that my result is only English or only Hebrew, obviously!*).

All of the documentation shows `LanguageCode` specified as a pipe-separated string, but if I specify more than 1 LanguageCode, I get this `Member must satisfy enum value set` exception.

Accepted Answer

The LanguageCode parameter is meant to be used when your audio file includes only one language. In the documentation, the pipe symbol represents "or" so it means that you should select one of choices.

But, there is a way to do what you want...

Using the parameter IdentifyMultipleLanguages in your transcription job enables automatic multi-language identification in your transcription job request. Use this parameter if your media file contains more than one language. If you include IdentifyMultipleLanguages, you can optionally include a list of language codes, using LanguageOptions, that you think may be present in your media file.

LanguageOptions is an array of strings and you can provide both 'en-US' and 'he-IL' in the array.
