# Standard Tasks

This table describes the standard tasks that are already defined in the tasks configuration file. You can run any of these tasks straight out of the box.

Task | Description
--- | ---
`AfpAddTrack` | Adds a new audio track to an audio fingerprint database.
`AfpDatabaseInfo` | Returns a list of all tracks that are currently stored in the specified database.
`AfpDatabaseOptimize` | Optimizes the internal indexing of the specified database. This task permanently removes files that have been tagged for deletion using the `AfpRemoveTrack` task, and optimizes lookup functions for newly added tracks.
`AfpMatch` | Receives audio data in an audio file or stream, and searches it for any indexed audio sections.
`AfpRemoveTrack` | Removes specified tracks from an audio fingerprint database.
`AudioAnalysis` | Runs all the audio preprocessing tasks that are supported by the `audiopreproc` module in a single task.
`AudioSecurity` | Detects and labels segments of audio that contain alarms, screams, breaking glass, or gunshots.
`ClippingDetection` | Analyzes an audio file for the issue of audio clipping.
`ClusterSpeech` | Clusters wide-band speech into speaker segments.
`ClusterSpeechTel` | Clusters telephony speech into speaker segments.
`ClusterSpeechToTextTel` | Clusters two speakers in a phone call, and uses the resulting speaker clusters to improve speech-to-text performance slightly by using speaker-sided acoustic normalization. Any telephony artifacts such as dial tones or DTMF tones are included, interspersed with the recognized words.
`CombineFMD` | Combines several phoneme track files, which can then be used for phrase search.
`CreateFMD` | Creates a phoneme time track (.fmd) file from a single audio file.
`DialToneIdentification` | Detects and identifies dial tones in audio.
`IvSpkId` | Performs iVector-based speaker identification on an audio file or stream.
`IvSpkIdDevel` | Processes one or more speaker ID feature files to generate scores for tuning iVector-based score thresholds.
`IvSpkIdDevelAudio` | Processes an audio file or stream to generate scores for tuning iVector thresholds.
`IvSpkIdDevelFinal` | Calculates the iVector score threshold based on one or more development files, and generates a new set of iVectors with the thresholds.
`IvSpkIdFeature` | Uses an audio file that contains sample speech from one person to create speaker ID feature files for use in iVector based template training, and template score threshold development.
`IvSpkIdEditThresh` | Modifies the threshold of a template file or a single template stored in an iVector template set file.
`IvSpkIdSetInfo` | Produces a log file that lists the contents of the specified iVector template file or template set file.
`IvSpkIdSetAdd` | Adds a number of iVector speaker templates to a single speaker set file.
`IvSpkIdSetDelete` | Removes a speaker template from an iVector template set file.
`IvSpkIdTrain` | Takes one or more speaker ID feature files containing speech data from the speaker to be trained, and creates a new iVector speaker template.
`IvSpkIdTrainAudio` | Takes an audio file or stream containing speech data from the speaker to be trained, and creates a new iVector speaker template file.
`LangId` | Receives audio data from a file or stream, converts it into language identification features, and identifies the languages.
`LangIdFeature` | Converts audio files in the relevant language into language identification feature (.lif) files, which are required for training classifiers.
`LangIdOptimize` | Optimizes the balance between language classifiers. After training, some classifiers might be stronger than others because of properties of the training material and the languages in question. The optimization process weights the language models so that weaker languages have increased accuracy, without compromising accuracy for stronger language models. This process improves consistent performance.
`LangIdTrain` | Reads in a set of language ID 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 it is present, how frequently it occurs.
`LMPerplexity` | Analyzes the perplexity of a sample text file, when given a specific language model.
`PhraseSearch` | Searches for a specified phrase or phrases in an audio file.
`PunctuateCtm` | Adds punctuation to any `.ctm` file.
`Scorer` | Scores the recognition transcript (such as that generated by the `SpeechToText` task), when given a reference transcript file.
`SearchFMD` | Searches a phoneme track file for one or more specified phrases.
`SegmentText` | Inserts whitespace between words in a text file (for languages that do not separate words with whitespace).
`SNRCalculation` | Calculates SNR levels across an audio file.
`SpeechSilClassification` | Segments an audio file into sections of speech, non-speech, and music.
`SpeechToText` | Converts an audio file or stream into a text transcript.
`SpeechToTextFilter` | Converts an audio file or stream into a text transcript and categorizes the audio so that you can remove any sections consisting of music or noise.
`SpeechToTextTelephony` | Transcribes a telephony audio file or stream, including dial tones and DTMF dial tones.
`TextNorm` | Takes a raw text transcription file and produces a normalized form (by removing punctuation, rewriting numbers as words, altering word cases, and so on).
`TranscriptAlign` | If a transcript is available for an audio recording, the transcript alignment function can place time locations for each word in the transcript. You can use this function to align subtitles with audio or video files.
`TranscriptCheck` | Checks how well a text transcript matches the audio data, and identifies large missing or erroneous sections.

For details about each task, including the required action and configuration parameters, see the IDOL Speech Server Reference.
