By requiring the coordination of various cognitive and motor processes, even a short sample of speech may provide a sensitive snapshot of cognition and functioning relevant to many disease areas. Speech offers rich insights into cognition and function and is affected by many psychiatric and neurodegenerative diseases. In this paper, we review recommendations for digital biomarker evaluation using speech-based biomarkers as an illustrative case.

We approach biomarker evaluation as a systematic series of studies that evaluate and quantify the suitability of a given biomarker and its context for use. Following Strimbu and Tavel, we prefer to use the term “evaluation” rather than “validation” to refer to the overall process of assessing a biomarker, since this is a continuous process and may not have a single, conclusive outcome. Systematic and rigorous evaluation of digital biomarkers is crucial to ensure that they are providing accurate measurement and can serve as suitable surrogate endpoints for detecting and monitoring disease. This approach holds considerable promise for yielding more sensitive measures of symptoms and disease, but many of these potential advantages must be borne out with empirical testing. The use of digital biomarkers facilitates frequent testing with its potential to provide richer and more detailed data. Importantly, the use of digital measures will facilitate remote testing, improving accessibility and reducing the risks inherent in visiting health care centers. They also offer a promising solution for known problems associated with current clinical tools, especially repeated assessment effects, interrater variability, time investment, and expense. For example, digital biomarkers are more ecologically valid measures than many current clinical assessments of cognition and function, allowing assessments to occur during everyday activities or with little instruction. Recent reviews have shown how digital measures will bring benefits to clinical research and practice. Research into digital biomarkers is an area of rapid growth in digital medicine. The examples in this paper focus on speech-based biomarkers, but they can be used as a template for digital biomarker development more generally. For each of these sections, we provide recommendations for the types of evaluation necessary for speech-based biomarkers and review published examples. Clinical validity involves verifying the correspondence of a measure to clinical outcomes which can include diagnosis, disease progression, or response to treatment. Analytical validation includes checking the accuracy and reliability of data processing and computed measures, including understanding test-retest reliability, demographic variability, and comparing measures to reference standards.

Verification includes assessing the quality of speech recordings and comparing the effects of hardware and recording conditions on the integrity of the recordings. The V3 framework describes 3 components of evaluation for digital biomarkers: verification, analytical validation, and clinical validation. This paper outlines and provides examples from the literature of evaluation steps for speech-based digital biomarkers, based on the recent V3 framework (Goldsack et al., 2020). As with many novel digital biomarkers, however, rigorous evaluation is currently lacking and is required for these measures to be used effectively and safely.
