Multilingual Speech Processing by Tanja Schultz, Katrin Kirchhoff

By Tanja Schultz, Katrin Kirchhoff

Tanja Schultz and Katrin Kirchhoff have compiled a accomplished evaluate of speech processing from a multilingual viewpoint. via taking this all-inclusive method of speech processing, the editors have integrated theories, algorithms, and methods which are required to aid spoken enter and output in a wide number of languages. Multilingual Speech Processing offers a finished creation to analyze difficulties and suggestions, either from a theoretical in addition to a realistic viewpoint, and highlights know-how that includes the expanding necessity for multilingual functions in our international community.

Current demanding situations of speech processing and the feasibility of sharing information and process elements throughout various languages consultant individuals of their discussions of tendencies, prognoses and open learn concerns. This comprises automated speech reputation and speech synthesis, but additionally speech-to-speech translation, conversation platforms, automated language identity, and dealing with non-native speech. The booklet is complemented by means of an outline of multilingual assets, vital learn developments, and genuine speech processing platforms which are being deployed in multilingual human-human and human-machine interfaces.

Researchers and builders in and academia with diverse backgrounds yet a standard curiosity in multilingual speech processing will locate a very good evaluate of study difficulties and strategies specified from theoretical and sensible perspectives.

  • State-of-the-art examine with an international viewpoint by means of authors from the us, Asia, Europe, and South Africa
  • The in simple terms accomplished creation to multilingual speech processing at the moment available
  • Detailed presentation of technological advances critical to protection, monetary, mobile and advertisement applications

Chapter 2 describes language characteristics in greater detail, including language distributions, speaker populations, and the typological classification of languages. The similarities and dissimilarities between languages are analyzed in terms INTRODUCTION 3 of spoken and written forms and their relation, and consequences for multilingual speech processing are discussed. S. and European perspectives. Multilingual data repositories as well as large ongoing and planned collection efforts are introduced, along with a description of the major challenges of collection efforts, such as transcription issues due to inconsistent writing standards, subject recruitment, recording equipment, legal aspects, and costs in terms of time and money.

Writing systems can be subclassified according to the types of graphemes they employ—in particular, the relationship between grapheme, sound, and meaning. Following Sampson (1985), we draw a basic distinction between logographic systems, which are based on semantic units (units of meaning), and phonographic systems, which are based on sound units. The former can be subdivided into morphemic and polymorphemic systems, and the latter fall into syllabic, segmental, and featural subtypes. 4 summarizes this classification, which is explained in detail below.

In a similar way, 16 CHAPTER 2. LANGUAGE CHARACTERISTICS the use of pitch information in the language (tone or intonation) determines whether and in what way fundamental frequency measurements are integrated into a speech processing system. Morphology The field of morphology describes the process of word formation in a language, which is the process of combining the smallest meaningful parts of the language (morphemes) to form larger words. Similar to the situation in phonology, we can distinguish between morphemes and morphs—the concrete realizations of morphemes—for example, −s, −z, and −es are all concrete instances of the PLURAL morpheme.
