Automated Analysis of Relative Fundamental Frequency in Continuous Speech: Development and Comparison of Three Processing Pipelines.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesRelative fundamental frequency (RFF) estimates laryngeal tension during speech, providing insights into vocal effort. Current methods to derive RFF from continuous speech require manual processing, hindering large-scale studies with ecologically valid speech productions. This research aimed to develop and evaluate three fully automated pipelines for RFF analysis from continuous speech, addressing this limitation.
methodsThree pipelines were compared: two modifications of an existing semiautomated approach [automated relative fundamental frequency (aRFF)-AP] and one novel pipeline replicating manual analysis. The pipelines were tested on speech samples containing vowel-consonant-vowel (VCV) utterances from 82 female participants with and without vocal fatigue complaints in the absence of phonotraumatic vocal fold changes. The pipelines automatically segmented VCVs and measured RFF. Manual measurements of a subset provided reliability and validity benchmarks.
resultsAll pipelines demonstrated good reliability (r ≥ 0.84) and validity when compared with manual analysis. They required minimal manual correction (<4%) for fricative identification. Notably, the novel aRFF-B pipeline rejected the fewest samples (10%-25%) while maintaining reliability and was able to leverage parallel computing.
conclusionsThree automated pipelines, especially aRFF-B, enabled time-efficient RFF analysis of large continuous speech data sets without manual intervention. This advancement can facilitate large-scale studies using RFF applied to continuous speech, potentially expanding its application in voice research and clinical practice.
