TLDR
The proposed algorithm builds a lexicon enriched with topic information in three steps: transcription of an audio stream into phone sequences with a speaker- and task-independent phone recogniser, automatic lexical acquisition based on approximate string matching, and hierarchical topic clustering of the lexical entries based on a knowledge-poor co-occurrence approach.

Command-based voice teleoperation of a mobile robot via a human-robot interface

TL;DR: In this article, a human-robot interface (HRI) is presented to teleoperate a robotic platform via the user's voice, where a speech recognition system is necessary.

Topic modeling for spoken documents using only phonetic information

TL;DR: Recent improvements in topic modeling using only phonetic information are presented and new results using recently developed techniques for discriminative training for topic identification used in conjunction with recent improvements in SOU learning are presented.

Constructing a Language From Scratch: Combining Bottom–Up and Top–Down Learning Processes in a Computational Model of Language Acquisition

TL;DR: A computational model of language acquisition is presented that is based on bootstrapping mechanisms and is usage-based in that it relies on discovered regularities to segment speech into word-like units and shows that top–down processing increases both understanding performance and segmentation accuracy.

Learning a semantic parser from spoken utterances

TL;DR: This paper presents an approach that learns a semantic parser in the form of a lexicon and an inventory of syntactic patterns from ambiguous training data which is applicable to spoken utterances and can be successfully applied to both spoken and written data.

A computational model for unsupervised childlike speech acquisition

Holger Brandl
TL;DR: A model for early infant speech structure acquisition implemented as layered architecture comprising phones, syllables and words and an integrated model for speech structure and imitation learning through interaction, that enables the authors' robot to learn to speak with an own voice.

Latent dirichlet allocation

TL;DR: This work proposes a generative model for text and other collections of discrete data that generalizes or improves on several previous models including naive Bayes/unigram, mixture of unigrams, and Hofmann's aspect model.

Latent Dirichlet Allocation

TL;DR: This paper proposed a generative model for text and other collections of discrete data that generalizes or improves on several previous models including naive Bayes/unigram, mixture of unigrams, and Hof-mann's aspect model, also known as probabilistic latent semantic indexing (pLSI).

The generative lexicon

TL;DR: It is argued that lexical decomposition is possible if it is performed generatively and a theory of lexical inheritance is outlined, which provides the necessary principles of global organization for the lexicon, enabling us to fully integrate the authors' natural language lexicon into a conceptual whole.
