Kaldi (software)
Kaldi is an open-source speech recognition toolkit written in C++ for speech recognition and signal processing, freely available under the Apache License v2.0. Kaldi aims to provide software that is flexible and extensible, and is intended for use by automatic speech recognition (ASR) researchers for building a recognition system. It supports linear transforms, MMI, boosted MMI and MCE discriminative training, feature-space discriminative training, and deep neural networks. Kaldi is capable of generating features like mfcc, fbank, fMLLR, etc. Hence in recent deep neural network research, a popular usage of Kaldi is to pre-process raw waveform into acoustic feature for end-to-end neural models. Kaldi has been incorporated as part of thCHiME Speech Separation and Recognition Challengeover several successive events. The software was initially developed as part of a 2009 workshop at Johns Hopkins University. Kaldi is named after the legendary Ethiopian goat herder Kaldi ...

Deep Neural Network
Deep learning (also known as deep structured learning) is part of a broader family of machine learning methods based on artificial neural networks with representation learning. Learning can be supervised, semi-supervised or unsupervised. Deep-learning architectures such as deep neural networks, deep belief networks, deep reinforcement learning, recurrent neural networks, convolutional neural networks and Transformers have been applied to fields including computer vision, speech recognition, natural language processing, machine translation, bioinformatics, drug design, medical image analysis, climate science, material inspection and board game programs, where they have produced results comparable to and in some cases surpassing human expert performance. Artificial neural networks (ANNs) were inspired by information processing and distributed communication nodes in biological systems. ANNs have various differences from biological brains.

Computational Linguistics
Computational linguistics is an Interdisciplinarity, interdisciplinary field concerned with the computational modelling of natural language, as well as the study of appropriate computational approaches to linguistic questions. In general, computational linguistics draws upon linguistics, computer science, artificial intelligence, mathematics, logic, philosophy, cognitive science, cognitive psychology, psycholinguistics, anthropology and neuroscience, among others. Sub-fields and related areas Traditionally, computational linguistics emerged as an area of artificial intelligence performed by computer scientists who had specialized in the application of computers to the processing of a natural language. With the formation of the Association for Computational Linguistics (ACL) and the establishment of independent conference series, the field consolidated during the 1970s and 1980s. The Association for Computational Linguistics defines computational linguistics as: The term "comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coffee Plant
''Coffea'' is a genus of flowering plants in the family Rubiaceae. ''Coffea'' species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste and are often juiced. The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. Cultivation and use There are over 120 species of ''Coffea'', which is grown from seed. The two most popular are ''Coffea arabica'' (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and ''Coffea canephora'' (known as "Robusta"), which accounts for about 20–40%. '' C. arabica'' is preferred for its sweeter taste, while ''C. canephora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaldi
Kaldi or Khalid was a legendary Arab Ethiopian goatherd who discovered the coffee plant around 850 CE, according to popular legend, show some artwork depicting him, after which it entered the Islamic world and then the rest of the world. Story In the 9th century a goat herder named Kaldi from Kaffa noticed that when his goats were nibbling on the bright red berries of a certain bush, they became very energetic, Kaldi then chewed on the fruit himself. His exhilaration prompted him to bring the berries to the nearest place of worship in the village. After a brief explanation, the head monk deemed the berries to be the "Devil’s work", and abruptly threw the berries into a nearby fire. Soon thereafter, a sensual and powerful aroma filled the room that could not be overlooked. The head monk, who had thrown them in the fire in the first place, ordered the embers be pulled from the fire and for hot water to be poured over them to preserve the smell. Upon drinking the mixture, they exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goatherd
A goatherd or goatherder is a person who herds goats as a vocational activity. It is similar to a shepherd who herds sheep. Goatherds are most commonly found in regions where goat populations are significant; for instance, in Africa and South Asia South Asia is the southern subregion of Asia, which is defined in both geographical and ethno-cultural terms. The region consists of the countries of Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.;;;;;;;; .... Goats are typically bred as dairy or meat animals, with some breeds being shorn for wool. The top six goat industry groups in the United States include: meat (includes show), dairy (includes show, pygmy and Nigerian dwarf), fiber or hair (angora, cashmere), 4-H, industrial (weed control, hiking/pack), and biotech (see Goat#Agriculture, Goats in agriculture). Companies using goats to control and eradicate Euphorbia virgata, leafy spurge, knapweed, and other toxic weeds have sprouted acros ...

FMLLR
In signal processing, Feature space Maximum Likelihood Linear Regression (fMLLR) is a global feature transform that are typically applied in a speaker adaptive way, where fMLLR transforms acoustic features to speaker adapted features by a multiplication operation with a transformation matrix. In some literature, fMLLR is also known as the Constrained Maximum Likelihood Linear Regression (cMLLR). Overview fMLLR transformations are trained in a maximum likelihood sense on adaptation data. These transformations may be estimated in many ways, but only maximum likelihood (ML) estimation is considered in fMLLR. The fMLLR transformation is trained on a particular set of adaptation data, such that it maximizes the likelihood of that adaptation data given a current model-set. This technique is a widely used approach for speaker adaptation in HMM-based speech recognition. Later research also shows that fMLLR is an excellent acoustic feature for DNN/HMM hybrid speech recognition models. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
