چکیده

Speech recognition systems based on or aided by articulatory features, such as place and manner of articulation, have been shown to be useful under varying circumstances. Recognizers based on features better compensate channel and noise variability. In this work we show that it is also possible to compensate for inter language variability using articulatory feature detectors. We come to the conclusion that articulatory features can be recognized across languages and that using detectors from many languages can improve the classification accuracy of the feature detectors on a single language. We further demonstrate how those multilingual and crosslingual detectors can support an HMM based recognizer and thereby significantly reduce the word error rate by up to 12.3% relative. We expect that with the use of multilingual articulatory features it is possible to support the rapid deployment of recognition systems for new target languages.

Integrating multilingual articulatory features into speech recognition

The use of articulatory features, such as place and manner of articulation, has been shown to reduce the word error rate of speech recognition systems under different conditions and in different settings. For example recognition systems based on features are more robust to noise and reverberation. In earlier work we showed that articulatory features can compensate for inter language variability...

Towards multilingual articulatory feature recognition with support vector machines

We present experiments on mono-lingual and cross-lingual articulatory feature recognition for English and German speech data. Our goal is to investigate to what extent it is possible to derive and reuse articulatory feature recognizers, whether particular features are better suited to this task. Finally whether this goal is practically achievable with the chosen machine learning technique and t...

Investigating the learning effect of multilingual bottle-neck features for ASR

Deep neural networks (DNNs) have become state-of-the-art techniques of automatic speech recognition in the last few years. They can be used at the preprocessing level (Tandem or BottleNeck features) or at the acoustic model level (hybrid Hidden Markov Model/DNN). Moreover, they allow exploiting multilingual data to improve monolingual systems. This paper presents our investigation of the learni...

Towards Improving Low-Resource Speech Recognition Using Articulatory and Language Features

In an increasingly globalized world, there is a rising demand for speech recognition systems. Systems for languages like English, German or French do achieve a decent performance, but there exists a long tail of languages for which such systems do not yet exist. State-of-the-art speech recognition systems feature Deep Neural Networks (DNNs). Being a data driven method and therefore highly depen...

Under-resourced speech recognition based on the speech manifold

Conventional acoustic modeling involves estimating many parameters to effectively model feature distributions. The sparseness of speech and text data, however, degrades the reliability of the estimation process and makes speech recognition a challenging task. In this paper, we propose to use a nonlinear feature transformation based on the speech manifold called Intrinsic Spectral Analysis (ISA)...
