Contrary to the English /r/, which has been extensively analysed, there is very little information on the trilled consonants in Spanish. These sounds are in general difficult to produce for young Spanish children and occur later (than other consonant sounds) in normal development. This paper describes acoustic measurements made on the trill productions in Spanish children with varying degrees of speech intelligibility. The spectral (frequency, amplitude, C-V ratio) and temporal characteristics… 
Second Language Acquisition of the Spanish Multiple Vibrant Consonant
TLDR
This study employed two experiments to investigate the characteristics of L2 acquisition of Spanish /r/ by adult native speakers of English and found a pattern of increasing ability to produce trills as proficiency level increased and patterns of both “categorical” and “gradient” acquisition.
Acoustic analysis of the rhotic contrast in chicagoland Spanish an intergenerational study
This paper reports on an acoustic analysis of the phonemic tap-trill contrast (/ɾ/-/r/) for first and second generation speakers of Mexican Spanish who live in the Chicagoland area. First, it is
Differences in Discriminating L2Consonants: A Comparison of Spanish Taps and Trills
Models of secondand cross-language speech (e.g., Perceptual Assimilation Model, Best, 1995; Speech Learning Model, Flege, 1995; Native Language Magnet Model, Kuhl, 1993) have shown that the degree of
The Acquisition of Allophonic Variation in Spanish as a Second Language
This study will examine the acquisition of the Spanish trill by adult Farsispeaking learners. It is generally agreed that trills are difficult segments to produce. They are difficult for L2 learners
The interaction of acoustic and orthographic input in the acquisition of Spanish assibilated/fricative rhotics
ABSTRACT There is growing evidence that exposure to orthographic input affects second language phonological acquisition. This study examined the effects of auditory–orthographic interactions on
A Spanish pilot investigation for a crosslinguistic study in protracted phonological development
TLDR
Pilot Spanish data for this study from two 4-year-old boys with protracted phonological development helped consolidate the Spanish word list for elicitation and led to questions for the ongoing study concerning word structure, multisyllabic words, liquids, fricatives and vowel sequences.
Discrimination and Identification of a Third Formant Frequency Cue to Place of Articulation by Young Children and Adults
Typically-developing children, 4 to 6 years of age, and adults participated in discrimination and identification speech perception tasks using a synthetic consonant–vowel continuum ranging from /da/
Second Language Acquisition of the Spanish Tap and Trill in a Contact Learning Environment
TLDR
This study reveals, through the results of a variable rule analysis, that the two most significant factors in accurate tap and trill articulation are its phonetic context and whether or not the participants had received adequate Spanish instruction prior to having lived abroad.
Assessing Rhotic Production by Bilingual Spanish Speakers
Due to its articulatory precision, the Spanish rhotic system is generally acquired in late childhood by monolingually-raised (L1) Spanish speakers. Heritage speakers and second language (L2)

The story of /r/
In describing sound changes, sound patterns and alternations in languages one clearly needs to refer to a natural class of r sounds, or rhotics. This phonological class encompasses sounds with a wide
Identification of synthesized [r-w] continua for adult and child speakers.
TLDR
This study focuses on the problem as manifested in the disordered production of [r] sounds, which is the comparison between adult speech and child speech, and synthesized child [ r] stimuli, which were identified by most subject considerably better than natural child [w] stimuli.
Temporal characteristics of "functionally" misarticulated /s/ in 4- to 6-year-old children.
TLDR
Results indicate that /s/ durations of misarticulating children are significantly more variable than those of normally articulating children, and that this difference is more striking in /s/-stop clusters than in the case of singleton /s/.

TLDR
F3 trajectory durations were similar across consonant contexts, suggesting that coarticulation of /r/ is achieved by overlap of a stable /r/-related articulatory gesture with gestures for neighboring sounds.

ABSTRACT This paper examines the voicing contrast for word-initial obstruents in a child whose functional misarticulation initially was characterized by a severe lack of contrasts normally used in

TLDR
Results indicated that the major resonances of the fricatives studied were higher than values reported for both male and female adult speakers.
