Artificial intelligence has been discovered to detect potential cancer indications in an individual's vocal tone, according to a recent study.
In a significant breakthrough, researchers have been exploring the use of artificial intelligence (AI) to detect early-stage laryngeal cancer through voice recordings. The study, published in the journal Frontiers in Digital Health, suggests that AI could potentially identify abnormal growths on the vocal cords, including laryngeal cancer, using short voice recordings [1][2][3].
The research team, led by Phillip Jenkins from Oregon Health and Science University in the United States, analyzed 12,500 voice messages from 306 people across North America [1]. They found subtle acoustic patterns like changes in pitch and loudness clarity in the analysis, which could indicate the presence of vocal fold lesions [3][5].
Jenkins and his team are confident that vocal biomarkers could be used to distinguish voices with lesions from those without them. However, the study's findings were limited due to the size of the dataset [1]. To overcome this, they recommend training AI models on larger datasets and testing them in clinical settings for both men and women [4].
Laryngeal cancer is the 20th most common cancer worldwide, affecting over a million people and causing approximately 1,00,000 deaths each year [6]. Symptoms include hoarseness and changes in voice lasting more than three weeks, sore throat, swelling, a lump in the neck, and ear and throat pain [7]. Early detection is crucial for better outcomes and survival rates, with survival rates ranging from 35 to 90 percent depending on early diagnosis [8].
The approach offers a noninvasive, scalable, and potentially low-cost method for early screening compared to the current invasive standards like video nasal endoscopy and biopsy [1][4]. Future prospects for AI in this area are optimistic but still in the early stages. Next steps involve expanding and ethically sourcing larger, diverse datasets to improve AI accuracy across different demographics and real-world conditions [4].
Researchers envision AI-powered voice analysis becoming part of routine health screening, enabling early warning for laryngeal pathology even before clinical symptoms appear [2][4]. Pilot clinical tests of these AI tools could begin within the next few years, potentially transforming early detection accessibility and improving patient outcomes worldwide by enabling earlier intervention [4].
In summary, AI-based voice analysis for early detection of laryngeal cancer is a developing field showing strong proof-of-principle evidence. It harnesses acoustic biomarkers to deliver a noninvasive, quick, and accessible screening option that, once validated, could significantly enhance early diagnosis and treatment of this serious disease [1][3][5].
