Computerized speech handling required simplified phonetic notations tailored per language

Evidence

Since the symbols used in the IPA – including a large set of symbols for phonetic units, markers for so-called suprasegmental features, additional notational features called diacritics, etc. – are not well suited to computerized representation, different modifications have been developed with simplified notation. For example, IPA-ASCII applies only to ASCII characters. Other such symbol sets are SAMPA (Wells, 1997), where speech units specific to a single language are designed individually, and Speech Synthesis Markup Language (W3C, 2004), which is an XML-based (extensive markup language) markup language for assisting the generation of synthetic speech in Web and other applications. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 569
