Definiciones basadas en el consenso para biomarcadores vocales: La Iniciativa Internacional VOCAL
medRxiv : the preprint server for health sciences
|December 17, 2025
Resumen
Se desarrollaron definiciones estandarizadas para biomarcadores vocales a través del consenso internacional. Este marco mejora la colaboración interdisciplinaria y avanza las tecnologías de salud basadas en la voz para uso clínico.
Área de la Ciencia:
- Informática Biomédica
- Ciencias del Habla y del Lenguaje
- Salud Digital
Sus antecedentes:
- Las tecnologías de la salud basadas en la voz están avanzando rápidamente.
- La falta de terminología estandarizada obstaculiza la investigación y la traslación clínica.
- Necesidad de un marco basado en el consenso para los biomarcadores vocales.
Objetivo del estudio:
- Desarrollar definiciones universalmente aceptadas para biomarcadores vocales.
- Establecer estándares y directrices a través de la iniciativa VOCAL.
- Facilitar la colaboración interdisciplinaria en la investigación de biomarcadores vocales.
Principales métodos:
- Estudio internacional de creación de consenso en múltiples etapas (iniciativa VOCAL).
- Colaboración entre redes norteamericanas (Bridge2AI-Voice) y europeas (eVoiceNet).
- Proceso de revisión iterativa con 24 expertos internacionales, culminando en un taller.
Principales resultados:
- Se estableció un modelo de continuo jerárquico de biomarcadores vocales.
- Se definieron términos desde conceptos amplios (biomarcador, biomarcador digital, biomarcador vocal) hasta dominios específicos.
- Se incluyeron medidas acústicas cardiorrespiratorias, de voz, del habla/articulatorias y cognitivo-lingüísticas.
Conclusiones:
- Proporciona un vocabulario compartido esencial para la comunicación interdisciplinaria.
- Mejora la calidad, eficiencia y el despliegue ético de las tecnologías de voz en la investigación.
- Sienta las bases para directrices y estándares para la utilidad clínica de los biomarcadores vocales.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
2.4K
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:21Larynx
4.0K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
2.0K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...
