Mumbling is often viewed as a sign of confusion or lack of confidence when speaking. However, communication can be improved by using alternative words that describe the same action. For instance, one could use the word "murmur" instead of mumbled, depicting a low-toned, inarticulate sound uttered softly. Another synonym for mumbled is "grumbled," which implies a slightly annoyed tone. Similarly, the word "slurred" portrays a hesitant, indistinct speech caused by alcohol or other drugs' influence or acute nervousness. Including synonyms for mumbled not only increases the range of vocabulary but also enables individuals to express different ideas and emotions with greater accuracy.
