Installing boost on Windows using MinGW-w64 (gcc 64-bit)

Introduction

Boost is easy when you are using headers or pre-compiled binaries for visual studio, but it can be a pain to compile from source on windows, especially when you want the 64-bit version of MinGW to use gcc/g++. This installation process should be thorough enough to simply copy and paste commands, but robust enough to install everything you need.

Note: if you need to install any of the libraries that need dependencies, see this great answer from stack overflow

Get files needed for install

Get the MinGW installer mingw-w64-install.exe from Sourceforge
Get the boost_1_68_0.zip source from Sourceforge
__Note: This should work perfectly w

2018: Speech2Vec: A Sequence-to-Sequence Framework for Learning Word Embeddings from Speech

Projects audio files that contains one word of speech into a hyper-dimension space just like Word2Vec. Uses "Force Aligment" to split audio into words (which requires text). Pad the audio segments with zeros, do MFCC, feed into encoder-decoder which uses RMSE. They also add noise to the signal and make the network denoise it. LibriSpeech 500 hour of audio. Not sure how it can incorporated in an ASR or TTS systems. The audio file has to be paired with a text otherwise Speech2Vec cannot split the audio file into words using "Forced Alignment" method. It is used to query if the spoken word is similar to an existing word in the corpus.

2016: Neural Machine Translation of Rare Words with Subword Units (BPE)

BPE data compression tool that combines most frequent pair of bytes with one. It works well with Named Entity, loadwords and morphologically complex words. Handles OOVs well and rare words. You can
