Output Options

The following parameters are used to refine the transcription output. Refer to output for more information on using the output parameter.

Table 1. Output Options





false (default), true

This option explicitly allows curl to perform "insecure" SSL connections and transfers. All SSL connections are attempted to be made secure by using the CA certificate bundle installed by default. This makes all connections considered "insecure" fail unless -k --insecure is used.

This option is only relevant when HTTPS URLs are provided for callback or utterance_callback.

Refer to http://curl.haxx.se/docs/sslcerts.html for more details on this parameter.


true (default), false, concat

Controls whether or not number words in transcribed text are converted into numeric digits and related conventional formats, including dollar amounts, wall-clock times, percentages, ordinals, and telephone numbers. For example, with numtrans set to true (the default), the words “forty two percent” would be transformed into the text “42%”.

Use the numtrans=concat option to ask the engine to perform more concatenation than usual.

Refer to numtrans for more information on this parameter.


true (default), false

Controls whether transcript text is punctuated or not. In most cases it is desirable to leave punctuation turned on, but there are special cases where it should be turned off. For example, if you are evaluating the Word Error Rate (WER) of Voci’s transcripts, punctuation must be disabled.

As of V‑Blaze version 7.1.0-1, setting punctuate=false will generate English output in lowercase.



Enables you to specify the URL of a callback server to which each utterance in a transcription result will be POSTed as it is transcribed. Using this option is mandatory for real-time speech processing. As used in the ASR engine, a callback is the address and (optionally) method name and parameters of a web application that can receive data via HTTP or HTTPS. In the ASR engine, callbacks are usually used to enable another application to receive and directly interact with the transcripts produced by the ASR engine.

Refer to utterance_callback for more information on this parameter.


false (default), true

Enables you to specify that output must be returned in a zip file.
