Sequence-to-Sequence (S2S) models recently started to show state-of-the-art performance for automatic speech recognition (ASR). With these large and deep models overfitting remains the largest problem, outweighing performance improvements that can be obtained from better architectures. One solution…
In the past, we adapted neural network based multilingual acoustic models using language codes. In this work, we study the extracted language codes and the language properties they encode: We use the codes to generate language prototype vectors, which represent the features of a language. Computing…
We summarize the accomplishments of a multi-disciplinary workshop exploring the computational and scientific issues surrounding the discovery of linguistic units (subwords and words) in a language without orthography. We study the replacement of orthographic transcriptions by images and/or translate…
In this work, we focus on multilingual systems based on recurrent neural networks (RNNs), trained using the Connectionist Temporal Classification (CTC) loss function. Using a multilingual set of acoustic units poses difficulties. To address this issue, we proposed Language Feature Vectors (LFV s) to…
Documenting unwritten languages is a challenging task, even for trained specialists. To help linguists in better and faster documenting new languages is the goal of the French-German ANR-DFG project BULB. To discover the phonetic inventory of a language the project follows three steps: estimating ph…
In particular for “low resource” Keyword Search (KWS) and Speech-to-Text (STT) tasks, more untranscribed test data may be available than training data. Several approaches have been proposed to make this data useful during system development, even when initial systems have Word Error Rates (WER) abov…
