A method is demonstrated for creating density-equalizing maps of IPA consonant and vowel charts, where the size of a cell in the chart reflects information such as the crosslinguistic frequency of the consonant or vowel. Transforming the IPA charts in such a way allows the visualization of interactions between phonetic features. Density-equalizing maps are used to illustrate a range of facts about consonant and vowel inventories, including the frequency of consonants and vowels and the frequency of common diacritics, and to illustrate the frequency of deletion and epenthesis involving particular consonants and vowels. Solutions are proposed for issues involving genealogical sampling, counting pairs of very similar phones, and counting diacritics in relation to basic symbols.

This paper describes changes to the extIPA (Extensions to the IPA) symbol set, the motivation for these changes, and areas where future changes by the IPA might be helpful to clinical transcribers. The extIPA symbol set was introduced some twenty-five years ago. Since that time, some minor changes have been introduced to the extIPA chart but no major rearrangement has been attempted. The 2010 Oslo meeting of ICPLA (International Clinical Phonetics and Linguistics Association) started a revision of the extIPA chart, and this process was recently completed. A revised extIPA chart was approved at the 2016 ICPLA meeting. The revision involved the addition, modification and removal of categories and symbols. All changes derive from the need to denote sounds encountered in disordered speech that were not covered by the original chart.

The ‘voice quality symbols’ (VoQS) transcription system for voice quality was introduced some 20 years ago, and no major revision has been undertaken since then. In this account we describe the first major revision of the VoQS chart, these changes being mostly in the form of additions to the section on phonation types, but include also changes to the layout of the supralaryngeal settings section. These reflect recent developments in the understanding of the physiological underpinnings of sounds produced in the larynx including certain phonation types.

In Ecuador there exists a dynamic language contact continuum between Urban Spanish and Rural Quichua. This study explores the effects of competing phonologies with an analysis of voice onset time (VOT) production in and across three varieties of Ecuadorian highland Spanish, Quichua, and Media Lengua. Media Lengua is a mixed language that contains Quichua systemic elements and a lexicon of Spanish origin. Because of this lexical-grammatical split, Media Lengua is considered the most central point along the language continuum. Native Quichua phonology has a single series of voiceless stops (/p/, /t/, and /k/), while Spanish shows a clear voicing contrast between stops in the same series. This study makes use of nearly 8,000 measurements from 69 participants to (i) document VOT production in the aforementioned language varieties and (ii) analyse the effects of borrowings on VOT. Results based on mixed effects models and multidimensional scaling suggest that the voicing contrast has entered both Media Lengua and Quichua through Spanish lexical borrowings. However, the VOT values of voiced stops in Media Lengua align with those of Rural and L2 Spanish while Quichua shows significantly longer prevoicing values, suggesting some degree of overshoot.

This paper is an acoustic study describing the vowel spaces of bilingual Quechua–Spanish speakers in Cochabamba, Bolivia, with a particular focus on the height of mid and high vowels, in order to explore longstanding questions about the nature of Quechua vowel categories. South Bolivian Quechua is generally described as phonemically trivocalic with high-vowel lowering in presence of uvular consonants, but there has been little acoustic study of vowel formant characteristics (Cerrón-Palomino 1987, Laime Ajacopa, Cazazola & Pairumani 2007). The current study quantifies previous impressionistic observations of the vowel system and describes the acoustic properties of the Quechua vowels. Eleven bilingual speakers of South Bolivian Quechua and Spanish were recorded in a Quechua translation task and a Spanish list-reading task. Results of Bayesian models indicate that Quechua high vowels do appear to undergo systematic lowering following uvular consonants, supporting earlier descriptions. The results also demonstrate that lowering is consistent throughout the duration of the vowels, challenging a purely coarticulatory motivation for the observed lowering pattern. The allophonic mid-vowels of Quechua and the phonemic high and mid vowels of Spanish also have formant characteristics that may differ from one another, providing evidence for the hypothesis that these bilingual speakers could potentially command two separate vowel systems with different bases of articulation. These findings are also relevant for questions related to the nature of three-vowel systems, and whether or not they may contain true mid-vowel allophones.

Spanish is a Romance language spoken by approximately 405,638,110 speakers in the world (Lewis, Simons & Fenning 2013). Two major varieties are distinguished, Peninsular Spanish (Spain) and the Spanish spoken in the Americas, although it is also spoken natively in some parts of Africa, and in the United States. Spanish in the Americas comprises several dialects well differentiated by variations in the lexicon, phonology and, more importantly, in intonational patterns. In Mexico 86,211,000 (88% of the population) use Spanish as their first language, and a significant number of indigenous people have Spanish as their second language. The variety illustrated here is representative of the speech of the educated middle-class population from the metropolitan zone (three female and three male speakers in their 30s), which has as its center Mexico City, the most densely populated urban area in the country with more than 20 million people according to the Mexican National Census (INEGI 2010).

Asturian (ISO 639), also known as Bable, Asturiano, Asturianu, Astur-Leonese or Leonese, is the vernacular language of Principality of Asturias, an autonomous community of just over one million inhabitants located in Northern Spain. Asturian is spoken by approximately 100,000 individuals within Asturias plus a few thousand more outside of this region. Historically, Astur-Leonese was spoken in parts of the Spanish provinces of León and Zamora and there are still remnants of it in Castilian Spanish. In addition, a variety of Asturian – called Mirandés – is currently spoken in the Portuguese province of Miranda de Douro, where it is a language co-official with Portuguese (Figure 1).

Although Spanish is a relatively unified language, in the sense that people from very distant locations manage to understand each other well, there are several phonetic phenomena that distinguish geographically separated varieties. The total number of native speakers of Spanish is above 400 million, and roughly 10% of them live in Argentina (Instituto Cervantes 2014). The accent described below corresponds to formal Spanish spoken in Buenos Aires, and the main allophones are indicated by parentheses in the Consonant Table. The recordings are from a 49-year-old college-educated male speaker, who has lived all his life in either the city of Buenos Aires or the province of Buenos Aires.
