31:19 (Y. Ali) “And be moderate in thy pace, and lower thy voice; for the harshest of sounds without doubt is the braying of the ass.”
20:44 (Y. Ali) “But speak to him mildly; perchance he may take warning or fear ((Allah)).”
Rasul Allah said, ‘Anyone who believes in Allah and the Last Day (of Judgment) should not harm his neighbor. Anyone who believes in Allah and the Last Day should host his guest generously. And anyone who believes in Allah and the Last Day should say what is good or keep quiet.’ Bukhari
A lower voice tone is often associated with authority, respectability, and power. It does not matter if the person with the lower voice tone actually possesses these qualities. We are taught from youth to respect people who speak with lower voice tones. While you cannot completely change your voice, there are ways you can lower your voice tone and improve how you speak. Difficulty: Challenging Instructions
Things You’ll Need: tape recorder
1 Record yourself talking. Nobody actually sounds like they think they sound. It is only through the painful process of listening to your own recorded voice that you can hear the defects. Make tape recordings of yourself during normal conversation when you forget the tape recorder is on. Keep your first recording for later comparison.
2 Listen for times in your speech when your voice rises to high tones. Notice the words, phrases, and subjects that prompt this higher voice tone. Everybody speaks with voice characteristics that are repeated every time we talk. If you can figure out which habits launch your speech into higher voice tones, you will know where to focus your efforts.
3 Slow down when you talk. The faster people talk, the higher their voice tone. When you are trying to lower your voice tone, focus on pronouncing every word deliberately. End sentences with a down-tone. Instead of your voice rising, like when asking a question, drop it lower.
4 Calm down when you talk. When people get excited, they have a higher voice tone. They also sound less authoritative. Focus on keeping yourself grounded and speaking with a nurturing quality. Try to calm others with your tone of voice.
5 Speak from down low. High voice tones resonate from up in the nose. Lower voice tones resonate deep in the throat. Test it yourself. Place one hand on your nose and another on your throat. Feel your nose vibrate when you speak in higher voice tones and your throat vibrate when you speak in lower voice tones. Drop your voice down there and you will feel a deeper resonance in your words.
6 Listen to yourself again on a tape recorder. This is the only way to determine whether you are making any progress. Play the tape recording at the same time as the recording made when you started trying to lower your voice tone. Do this once per week to gauge your results.
