LangIdSegWav Reads in data from an audio file and converts it into language identification features. IDOL Speech Server processes the data in fixed-sized chunks, and returns the language identification results for each chunk.
LangIdTrain Reads in a set of language identification feature files created from audio representing a single language (using the LangIdFeature task), and uses this data to train a new language classifier.
LanguageModelBuild Builds a new language model from a set of text files.
LmListVocab Lists the most common words in the specified language model.
LmLookUp Verifies whether a specified word is present in the vocabulary of a particular language model and, if so, how frequently the word occurs.
LmPerplexity Analyzes the perplexity of a sample text file, when given a specific language model.
Scorer Scores a speech recognition transcript (such as that generated by the SpeechToText task), when given a reference transcript file.
SearchFMD Searches for specified phrases in a phoneme time track file.
SegmentText Inserts whitespace between words in a text file (for languages that do not separate words with whitespace).
SegmentWav Attempts to segment audio into sections by speaker even if no trained speakers exist in the system.
SidPackage - Deprecated Packages a set of trained speaker models into a single speaker classification file.
SidTrain - Deprecated Uses an audio file to create or update a speaker training file.
SidTrainFinal - Deprecated Uses a base model and one or more speaker training files to generate a speaker template file.
SNRCalculation Analyzes the signal-to-noise levels across an audio file.
SpeechSilClassification Segments audio by contents: either speech, non-speech, or music.
SpkIdDevel Processes speaker ID feature files to generate scores for tuning model thresholds.
SpkIdDevelFinal

Estimates the thresholds for a set of speaker templates.

SpkIdDevelStream Creates or updates a development (.atd) file for an audio stream.
SpkIdDevelWav Creates or updates a development (.atd) file for an audio file.
SpkIdEvalStream Analyzes an audio stream to identify any sections where the trained speakers are present.
SpkIdEvalWav Analyzes an audio file to identify any sections where the trained speakers are present.
SpkIdFeature Creates a speaker ID feature file.
SpkIdSetAdd Takes one or more audio template files, and adds them to an audio template set file.
SpkIdSetDelete Removes a template from an audio template set file.
SpkIdSetInfo Retrieves information on an audio template set file.
SpkIdTrain Uses one or more feature files to train a speaker template.
