Amphibians are considered as true voice producers. Justify.

Explanation

### Step-by-Step Solution:

1. **Introduction to Amphibians**: Amphibians, such as frogs and toads, are unique animals that can live both in aquatic (water) and terrestrial (land) environments. This dual habitat is significant in their development and physiology.

2. **Development of the Larynx**: Amphibians are considered true voice producers primarily because they possess a specialized structure known as the larynx, commonly referred to as the voice box. The larynx is located in the throat and is responsible for sound production.

3. **Mechanism of Sound Production**: The larynx produces sound through the vibration of vocal cords. When air passes through the larynx, it causes the vocal cords to vibrate, generating sound. This is a crucial adaptation that allows amphibians to communicate, especially during mating seasons.
