A vixen singing voice develops from incomplete contact between the vocal cords and nodules, calluses, polyps, or ulcers on the vocal cords. You can simulate a slightly scratchy singing voice by tensing your neck and expelling a lot of air as you sing. However, this technique can cause long-term damage to your voice. If you take this risk, be sure to take the necessary steps to ensure the safety of your vocal cords.
Steps
Method 1 of 2: Sing in a slightly raspy voice

Step 1. Warm up your voice
Before attempting to sing with a slightly raspy voice, you should warm up properly. Try starting with breathing exercises and then moving on to scales. After finishing, you can keep heating with vibrations and hums.

Step 2. Tense your neck while singing
When there is incomplete contact between the vocal cords, a scratchy sound is produced. You can have a raspy singing voice by tensing your neck and expelling a lot of air as you sing. This will prevent the vocal cords from coming into full contact, and will result in a slightly scratchy singing voice.
Singing or recording a couple of songs using this technique is fine, but you shouldn't sing, or record an entire album or concert as it can cause long-term damage to the vocal cords

Step 3. Mimic a coughing sound to reach lower-range voices
If you're singing near the bottom of your vocal range, you can combine your singing voice with the raspy sound of a cough. Try coughing a few times. Identify the screeching deep in the throat that is responsible for the cough. Now recreate this squeak as you sing.

Step 4. Use your saliva
One way to produce a raspy voice is to create a significant amount of saliva or phlegm in the back of the throat. Then, start singing with a growling voice. Tighten your throat muscles enough to restrict the flow of air with the phlegm. Your throat should feel like a low-pitched growl.

Step 5. Hire a voice coach
Singing in a slightly raspy voice can damage your vocal cords. To ensure you don't end up with long-term damage, you should enlist the help of a professional who can guide your forays into raspberry. Find voice trainers in your area, ask them about their teaching methodologies, and arrange a starter singing class.

Step 6. Use technology
You don't have to screw up your voice to get that slightly scratchy sound you're after. Try to use technology. For example, you can record a song with your normal voice and then ask a sound engineer to enhance the recording so that your voice sounds scratchy. This will protect your vocal cords and give you the scratchy recording you want.
Method 2 of 2: Use Your Voice Wisely

Step 1. Be aware that you can injure your vocal cords
Singing in a raspy voice can cause long-term damage to the vocal cords. This is especially true if you sing in a raspy voice, which can strain your vocal cords. Voice problems, such as vocal nodules and vocal polyps, can develop if you abuse or use your voice too much.

Step 2. Know when to stop
It's important to keep your vocal cords safe when trying to develop a slightly raspy singing voice. If your throat is sore or dry, you should not sing. You should also stop singing in a raspy voice if your voice seems tired.
You can alleviate a dry throat by drinking at least 8 glasses of water a day, resting your voice, and drinking warm lemon water

Step 3. Sing within your vocal range
Using the extremes of your vocal range, such as singing too high or too low, can put your vocal cords at risk. This is also true if you are trying to sing very low or very soft. Instead, sing within your natural vocal range.

Step 4. Stay hydrated
Making sure your body is hydrated is an important part of singing safely. Make sure you drink 8 glasses of water every day. Limit your consumption of alcohol and caffeine, as both can dry out and irritate your vocal cords. You can also use a humidifier at home.
