The utterances Array

The top-level utterances element contains an array of speech segment information. Each utterances array consists of the following elements.

Table 1. Data contained in the utterances Array

Object	Availability	Type	Definition
emotion	All	value	Emotional intelligence consists of both acoustic and linguistic information. Events can be given the following values: Positive Mostly Positive Neutral Mostly Negative Negative
confidence	All	value	A measure of how confident the speech recognition system is in its utterance transcription results. Range between 0 and 1 1 is most confident
end	All	value	End time of the utterance in seconds
recvtz	All	array	An array containing two values: time zone abbreviation of the timezone in which the ASR engine is running offset in seconds from UTC for the time on the ASR engine
sentiment	All	value	Utterance-level linguistic sentiment value: Positive Mostly Positive Neutral Mostly Negative Negative Mixed (contains both Positive and Negative in the file)
gender	All	value	Gender prediction of the speaker
rawemotion	All	value	Acoustic emotion values (version 7.1+): ANGRY NEUTRAL HAPPY Acoustic emotion values (prior to version 7.1): NONANGRY ANGRY
sentimentex	All	array	Contains sentiment information for each utterance [0][0] = Positive phrase counts [0][1] = Negative phrase counts in utterance [1][*] consist of an array of sentiment segments where [0] = ‘+’ or ‘-‘ for Positive and Negative, and [1] is the position range of the phrase [0] is beginning and [1] is end position
start	All	value	Start time of the utterance in seconds
donedate	All	value	Date and time the utterance transcription was completed by the speech-to-text engine
recvdate	All	value	Date and time the utterance was received by the speech-to-text engine
events	All	array	Contains information about individual words. Each element is a word object that contains the following values: confidence: word level transcription confidence value between 0 and 1 end: end time of the word in seconds start: start time in seconds word: normalized word. wordex: raw dictionary word. This value is often used to disambiguate different pronunciations that have the same spelling. For example: "events": [ { "confidence": 0.69, "end": 2.32, "start": 1.81, "word": "Stephanie" }, { "confidence": 0.76, "end": 2.74, "start": 2.32, "word": "so" }
metadata	All	object	Speaker information of the utterance. Each object contains the following values: channel: channel number model: model that decoded the utterance source: audio file name nsubs: (V‑Blaze 7.1+) count of substitutions applied for the utterance, not including `numtrans` counts. uttid: utterance segment number substinfo: (V‑Blaze 7.1+) substitutions detail included when `substinfo=true` nsubs: (V‑Blaze 7.1+) count of substitutions applied for the utterance, including `numtrans` counts. For example: "metadata": { "uttid": 1, "substinfo": { "subs": [ [ 19.56, 20.14, [ { "source": "subst_rules", "end": 20.14, "sub": "persona => /Persona/", "rule": "0", "start": 19.56 } ] ] ], "nsubs": 1 }, "source": "spa-eng-sample.wav", "channel": 0, "model": "spa3:travel", "nsubs": 1 } "metadata": { "source": "spa-eng-sample.wav", "model": "eng1:callcenter", "uttid": 0, "channel": 0 }
