Request Payload

This sub-page helps the integrator to understand various different types of request payload based on the individual task or combination of tasks in that sequence that integrator wants to do.

Request Payload for Individual Task

        {

        ]
    }
}

This response contains 2 major parameters listed below and detailed further down the section:

  1. pipelineTasks

  2. inputData

Parameter: pipelineTasks

Type: Array This parameter takes an array of tasks, in the form of dictionary of taskType and config, that are to be done by the integrator. In the above example, pipelineTasks takes only one dictionary (line 3-13) because integrator wants to do only ASR. taskType parameter takes String that takes the value asr

config parameter takes a Dictionary that contains following parameters:

audioFormat parameter accepts format of the audio which was recorded by the application.

  • For Android, wav is preferred and

  • For iOS, wav or flac is preferred.

However, the Server also accepts other well -known formats such as mp3.

Sampling Rate is determined by the application at which the audio is recorded. The Server accepts a minimum value of 8000 for samplingRate parameter.

Parameters other than taskType, serviceId and config are optional.

Parameter: inputData

inputData Parameter takes the actual input from the integrator on which the individual task has to be done. It can take the input either via input parameter or audio parameter depending on the task to be done. Since ASR is done on audio input data, for ASR,

  • input parameter is optional, of no use for ASR but

  • audio parameter is mandatory.

audio parameter takes audioContent parameter which accepts base64 String of the actual audio captured.

If audioFormat or/and samplingRate parameter is/are sent, integrator should make sure that these values correspond to the actual recorded audio.

For ASR, language parameter only takes sourceLanguage which accepts of the language.

serviceId parameter is obtained from the Pipeline Config Call as described .

For Translation, language parameter takes both sourceLanguage and targetLanguage which accepts of the language.

serviceId parameter is obtained from the Pipeline Config Call as described .

For TTS, language parameter only takes sourceLanguage which accepts of the language.

serviceId parameter is obtained from the Pipeline Config Call as described .

Therefore, the language code for ASR that is to be inserted in Line 7, shall be hi, i.e., code for Hindi. Once this Hindi digital text is generated, the same shall be translated to Marathi, therefore the source language code for Translation that is to be inserted in Line 18, shall also be hi, which means that language code in Line 7 and Line 18 shall be same.

For Target Language the code to be inserted in Line 19 shall be mr, i.e., code for Marathi.

Understanding of all other parameters remains same as described above in .

Therefore, the source language code for Translation that is to be inserted in Line 7, shall be hi, i.e., code for Hindi. The target language code to be inserted in Line 8 shall be mr, i.e., code for Marathi.

Understanding of all other parameters remains same as described above in .

Therefore, the language code for ASR that is to be inserted in Line 7, shall be hi, i.e., code for Hindi. Once this Hindi digital text is generated, the same shall be translated to Marathi, therefore the source language code for Translation that is to be inserted in Line 18, shall also be hi, which means that language code in Line 7 and Line 18 shall be same.

The target language code to be inserted in Line 19 shall be mr, i.e., code for Marathi.
