Represents in-memory audio data of a certain (convertible) representation. Attributes ---------- audio_type : str See `__ini

This is a POD but if you want memcmp to return the same as operator==, call ZeroRemaining first.

In-memory labeled audio sample representing an utterance. Derived from util.audio.Sample and used by sample collection readers and writers.

Test values aligned to 8 bytes.

A class that atomically increments a counter

Audio data file wrapper that ensures that the file is loaded with the correct sample rate, channels, and width, and converts the file on the

End of file reached.

Limits unbound ahead-processing of multiprocessing.Pool's imap method before items get consumed by the iteration caller. This prevents OOM iss

Input Iterator over lines. This allows for (StringPiece l : FilePiece("file")) in C++11. NB: not multipass.

Old binary files built on 32-bit machines have this header. TODO: eliminate with next binary release.

Proxy for an entry except there is some extra cruft between the entries. This is used to sort (n-1)-grams using the same memory as the sorted n-grams

Handle all the orders of a single model at once.

Wrapper around python map() output object that preserves the original collection length by implementing __len__.

Parameters stored in the header of a binary file.

This populates the ln_unigrams_ matrix. It can (and should for efficiency) be run in the same scan as JointOrderCallback.

Class wrapping a stt stream. The constructor cannot be called directly. Use :func:`Model.createStream()`

Represents a 128bit type. This class should be replaced by a native type on platforms that support 128bit integers.

(void*)-1 is MAP_FAILED; this is done to avoid including the mmap header here.

Level of complaining to do when loading from ARPA instead of binary format.
