Why Does My Voice Sound Different on Recording and Treatment Options

Every so often, I have a patient who presents to my office with a complaint that their voice sounds different on recording than what they themselves hear.

In particular, singers who come in state specifically that their vocal recordings sounds slightly flat when they thought they were singing in perfect pitch.

So why does this happen? Unfortunately, it is physics and fundamentally integrated to how the ear, skull, and sound transmission work. In other words, it can't be "treated" with surgery or medications.

What other people hear when you sing or talk is air conducted sound that gets transmitted through the ear canal, eardrum, middle ear bones, and ultimately to the cochlea hearing organ (pathway A). Image modified from Wikipedia.

The sound the individual singer/talker hears is not only sound transmitted via the air (pathway A) but also by vibration of the skull itself directly to the cochlea hearing organ bypassing the outer and middle ear completely (pathway B). The mechanical properties of the skull enhance the deeper, lower-frequency vibrations.

Therefore, when a talker/singer listens to a recording of their voice speaking/singing, the bone-conducted pathway that they consider part of their “normal” voice is eliminated, and they hear only the air-conducted component in unfamiliar isolation (what everybody else actually hears).

SO... what is a singer/talker to do if they are disturbed by the way they sound to others? Particularly, what is a singer to do when they always sing a little flat when they truly think they are singing in pitch?

One can wear earplugs in order to hear only bone-conducted vibrations and get used to their alter-voice and undergo speech/voice therapy. OR... accept that their voice IS different.

For singers, I highly recommend using HearFones Headsetwhich is a funny looking head device that allows an individual singer to hear what they really sound like and more importantly what the audience would hear! In addition, while using HearFones, the singer would be able to hear himself more predominantly over the rest of the ensemble thus helping him to improve the quality of his/her individual vocal quality output.

Over time, singers will be able to automatically adjust their singing such that they no longer will need such a device to sing in tune with others when in familiar surroundings. BUT... in new environments (new concert hall, outdoor arena, etc), it is not unusual that their singing may become off again...

This is why professional singers often wear earpieces that convey sounds recorded by microphones placed in the audience... and also why they sometimes sound flat and out-of-tune when they don't!

It's also why it is VERY important to rehearse in a new place before a concert.

TV Show SMASH Portrays Ivy With Vocal Issues

In last night's episode (Episode 106: Chemistry) of the new hit TV drama SMASH, the main character Ivy who plays Marilyn Monroe in the show developed laryngitis that affected her ability to sing clearly, especially in the high registers. However, her speaking voice did sound normal.

To treat this condition, she was given prednisone which did help her voice, but suffered unfortunate side effects of mood lability, hallucinations, insomnia, etc.

Did the show accurately portray what actually happens in real life?

Yes...

Laryngitis

Ivy probably did suffer laryngitis, but more in the sense of pre-nodule formation (otherwise known as vocal cord swelling) from vocal overuse given how much singing she has been doing. With such "pre-nodule" formation, the singer is able to sound perfectly normal when talking, but suffers from pitch breaks and onset delays in the high range, especially when singing quietly. Watch a video and audio demonstrating this phenomenon.

I should also point out that this problem is also under-recognized by medical professionals including ENTs... When such singer/patients with vocal cord swelling present complaining of hoarseness, they sound normal... talk normal... and for all intensive purposes seem to be making up their perceived raspy voice.

A simple test to demonstrate vocal cord swelling is to have the singer sing a song at a high pitch (octave above middle C), but to sing the song very quietly. I typically have patients sing Happy Birthday. Listen for any vocal quality problems.

Even though the vocal issue is only in the high range, for professional (and amateur) singers, such "minor" vocal raspiness is a HUGE problem. Consider this... if this patient is singing a solo for a performance where there's several hundred people in the audience... it's hard enough to sing a solo just from nervousness. Now add the concern that you have no idea what your voice is going to do in that one part of the song where it goes high. Confidence is key to a good performance and with an undependable voice, confidence is lost and the performance overall suffers.

Prednisone

Is prednisone really as good as the show suggests? Yes... including the side effects, though they did stretch the side effects some.

Typically steroids provide almost immediate (within 4-12 hours) resolution of vocal cord swelling and inflammation. Problem is, it only works for a short period of time.

I typically prescribe decadron rather than prednisone as I feel it works faster, better, and more reliably than prednisone. I also prescribe it judiciously.

Judiciously means I prescribe it if there's a single major concert or single audition that is very important to the singer. I typically prescribe a single large dose to be taken the night before.

If it is a singer who is undergoing a series of auditions over a short period of time, I may prescribe a week long course of steroids to maintain its good effects.

The USUAL common side effects are reflux, insomnia, mood lability, and jitteriness. However, for those who are sensitive to medications can suffer many of the side effects experienced by Ivy.

NOW... for the problem with steroids beyond the side effects... Its effects are temporary and the better way of treating vocal cord swelling is behavioral changes as one can't just keep prescribing steroids indefinitely. It is much like giving morphine to a football player to mask the pain of a sprained ankle so he can still keep playing football. MORE vocal injury can occur while taking the steroids!

With steroids, I usually also recommend restricted voice use (strict voice use is even better). What this means is talk ONLY when you MUST talk and with low energy if you do. NO social talking, no whispering, no yelling, no raising voice, etc. Strict voice rest is when you are not even talking at all.

Also, work with a singing voice therapist.

What is the Voicebox Doing When You Scream? Yodel?

In the same spirit of a recent TEDMED talk by Nate Bell and re-published on CNN Jan 12, 2012 whereby he performed various beatboxing noises while stroboscopy was performed, I decided to record a similar video with a person performing various unusual human vocalizations to see what happens.

For those who don't know what stroboscopy is, click here.

Such vocalizations recorded included various types of human screams and a yodel.
