For a comprehensive evaluation and personalized advice, it would be best to consult with a speech therapist or an otolaryngologist (ear, nose, and throat specialist). Here are a few general tips that may help:
Relaxation techniques: Tension and anxiety can affect your voice. Practice relaxation techniques such as deep breathing, meditation, or yoga to help reduce any physical or mental tension that might be impacting your ability to speak loudly.
Posture and breathing: Good posture and proper breathing technique can help support your voice. Stand or sit up straight, allowing your lungs to fully expand, and breathe deeply from your diaphragm rather than shallowly from your chest.
Vocal warm-up exercises: Prior to speaking or engaging in conversations, warm up your voice with gentle exercises. This can include humming, lip trills, tongue exercises, or vocal sirens. These warm-up routines can help relax your vocal cords and prepare them for speaking.
Hydration: Drink enough water throughout the day to keep your vocal cords hydrated. Hydration is crucial for maintaining vocal health.
Voice projection exercises: Practice projecting your voice by speaking from your diaphragm rather than your throat. Imagine your voice emanating from your abdomen or chest, allowing it to resonate and carry better.
Voice training or therapy: Consider seeking professional help from a speech therapist or voice coach who specializes in voice training. They can assess your specific situation and provide you with exercises and techniques tailored to your needs.
Remember, these are general suggestions, and the underlying cause of your voice change may require a more in-depth evaluation. Seeking professional guidance is important for an accurate diagnosis and personalized advice.
