1. **Understanding the Symptoms**

- **Difficult Breathing:**  
     This is a general description indicating that a person is experiencing trouble with breathing. It is often reported by patients as feeling like they cannot get enough air.

- **Dyspnea:**  
     This is the medical term for the subjective sensation of breathing discomfort. It is what many patients describe as “shortness of breath” or “difficulty breathing.” Formally, we denote dyspnea as the feeling:
     $$
     \text{Dyspnea} = \text{Subjective sensation of breathing discomfort}
     $$
     
   - **Tachypnea:**  
     This term refers to an abnormally rapid breathing rate. For an average adult at rest, a normal respiratory rate is approximately $$12$$ to $$20$$ breaths per minute. Tachypnea is typically defined when the rate exceeds this range, such as:
     $$
     \text{Tachypnea: Respiratory rate} > 20 \text{ breaths per minute}
     $$
     
   - **Dysphonia:**  
     This refers to an abnormality in the voice, such as hoarseness or difficulty speaking, which can result from lesions or functional issues involving the larynx (voice box).

2. **Connecting the Findings**

- When a patient presents with **difficult breathing** (or **dyspnea**) and **tachypnea**, it indicates that there is some compromise in normal respiratory mechanics or gas exchange, prompting the body to increase the breathing rate.
   - The presence of **dysphonia** suggests involvement of the larynx. This could point to conditions that not only affect breathing but also impact the vocal cords. For example, disorders such as vocal cord paralysis, laryngeal inflammation, or other laryngeal pathologies may produce both respiratory symptoms and voice changes.

3. **Clinical Considerations**

- **Respiratory Compromise:**  
     The combination of dyspnea and tachypnea often indicates that the respiratory system is under stress, whether due to lung pathology, airway obstruction, or neurological control issues.
   - **Laryngeal Involvement:**  
     The added symptom of dysphonia directs attention to the larynx. In clinical practice, one might evaluate the vocal cords and surrounding structures using techniques such as laryngoscopy to determine if there is nerve involvement (e.g., recurrent laryngeal nerve paresis) or intrinsic laryngeal disease.
   - **Correlation:**  
     The symptom constellation in a patient would prompt an investigation into both pulmonary function and laryngeal integrity. For instance, if the dysphonia is due to vocal cord dysfunction, it may contribute to airway compromise, exacerbating breathing difficulties.

4. **Summary**

- The symptoms can be summarized as follows:

$$
     \begin{array}{ll}
     \textbf{Difficult Breathing/Dyspnea:} & \text{Patient’s subjective feeling of inadequate breathing.} \
     \textbf{Tachypnea:} & \text{An increased respiratory rate (typically } >20 \text{ breaths per minute in adults).} \
     \textbf{Dysphonia:} & \text{Abnormal voice quality or hoarseness indicating laryngeal involvement.}
     \end{array}
     $$

- A physician would integrate these findings to explore potential respiratory and laryngeal diseases, ensuring that both lung function and laryngeal structure are carefully evaluated.

The patient is experiencing difficulty breathing, rapid breathing, and hoarseness. This suggests that there may be issues with both the respiratory system and the larynx, possibly due to conditions affecting the lungs, airways, or vocal cords.
