SpeechCases
SpeechCases[audio,form]
gives a list of cases of text identified as being of type form that appear in the transcription of audio.
SpeechCases[audio,{form1,form2,…}]
gives an association of results for all the types formi.
SpeechCases[audio,formspecprop]
gives the specified property for each result found.
SpeechCases[audio,formspec{prop1,prop2,…}]
gives a list of properties for each result found.
SpeechCases[audio,spec,n]
gives the first n cases found.
Details and Options
- SpeechCases[{audio1,audio2,…},…] gives cases for each audioi.
- Identification type form can be:
-
"type" any text content type (e.g. "Noun", "City") Entity[…,…] a specific entity of a text content type form1form2… - form matching any of the formi
Containing[outer,inner] forms of type outer containing type inner Verbatim["string"] a specific string to be matched exactly pattern a string pattern to be matched - Possible choices for the property prop are:
-
"String" string of the identified text (default) "Position" start and end position of the string in text "Probability" estimated probability that the identification is correct "Interpretation" standard interpretation of the identified string "Snippet" a snippet around the identified string "HighlightedSnippet" a snippet with the identified string highlighted f apply f to the association containing all properties {prop1,prop2,…} a list of property specifications - The following options can be given:
-
AcceptanceThreshold Automatic minimum probability to accept identification Masking All interval of interest PerformanceGoal Automatic favor algorithms with specific advantages TargetDevice "CPU" whether CPU or GPU computation should be used for entity detection VerifyInterpretation False whether interpretability should be verified - SpeechCases uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.
- SpeechCases may download resources that will be stored in your local object store at $LocalBase, and that can be listed using LocalObjects[] and removed using ResourceRemove.

SpeechCases is effectively calling TextCases on the result of SpeechRecognize:
SpeechCases supports the same identification types as TextCases:
They identify the same substrings for a given type and transcription:
Possible Issues (1)
The ability of SpeechCases to return an interpretable result is limited by the quality of the speech transcription:
See the transcription generated by SpeechRecognize:
The mistranscription of "Bergen" cannot be interpreted as a city in Norway:
