LSVT LOUD vs SPEAK OUT! Which is better?
LSVT LOUD® and SPEAK OUT!® are two of the most well-regarded Voice Treatment approaches for patients with Parkinson’s disease.
Both are evidence-based and have a clear track record of helping patients maintain their therapeutic gains. Both also provide high-quality training for Speech-Language Pathology professionals.
Between these two very good options, which should you spend your precious time and energy learning? While the answer depends on each person, we put together a summary to help you decide.
We cover each approach’s goal, how it works, the basic protocol, and details of how to become trained or certified. We also link to other helpful resources, including videos, websites, and journal articles.

LSVT LOUD (Lee-Silverman Voice Treatment)
What’s the Goal?
The goal of LSVT LOUD is to train patients to speak louder. More specifically, to speak at a “normal” loudness level.
The treatment does this by helping patients recognize how loud or soft they sound to other people. The goal is a life-long ability to use a stronger voice through continued practice, even after treatment is completed.
Some patients treated with LSVT LOUD also experience improved articulation and swallowing abilities.
This indicates that these related but untrained movements generalized—a sign of motor learning in action. Read more about the 9 Principles of Motor Learning for Speech-Language Pathologists.
How Does it Work?
Three Key Strategies
- The only treatment target is Vocal Loudness (amplitude)
- Intensive and High Effort. Patients are encouraged to continually work harder.
- Sensory Re-calibration. Through sensory feedback, patients learn to recognize that their louder, stronger voice sounds “normal.” This increases the likelihood that they’ll use this louder voice outside of therapy—that it becomes their normal voice.
Intensive Treatment Schedule
LSVT LOUD consists of 16 sessions. Over the course of 4 weeks, the therapist provides 1-hour sessions four times per week.
Patients are given daily homework.
Trained therapists have the option to provide treatment via real-time videoconferencing.
Basic LSVT LOUD Protocol
- The patient says “ah” in a loud voice (not shouting) for as long as they can.
- The patient reads 10 functional phrases (things they say in everyday life) in a loud voice.
- The patient says “ah” in a slightly high-pitched and loud voice for 3 seconds.
- The patient says “ah” in a slightly low-pitched and loud voice for 3 seconds.
- The patient reads aloud (increasingly complex material) in a loud voice for 5+ minutes.
- The patient completes daily exercises once a day during therapy days and twice a day during off-therapy days.
- The patient continues daily exercises after the program ends.
- Cueing for LSVT LOUD is simple: Ask the patient to “do what I do” and model the appropriate loudness.
- Prolonged or specific verbal instructions are not recommended. For example, don’t explain, “That wasn’t quite loud enough. You should tense your ab muscles and take a big breath from your stomach.” Stick with “do what I do.”

SPEAK OUT! is a voice treatment approach developed by the Parkinson’s Voice Project.
The goal of SPEAK OUT! is for people with Parkinson’s disease to produce a stronger, clearer voice.
This approach is based on the principles of motor learning and on the understanding that people with Parkinson’s disease have improved speech when they learn to speak with intention (versus using automatic motor behaviors).
Automatic speech is believed to be more impacted by Parkinson’s disease—hence the emphasis on intentional speech.
How Does it Work?
During SPEAK OUT! treatment, a therapist guides the patient through a series of speech, voice, and cognitive exercises. These exercises strengthen the muscles used for speech and swallowing. Patients follow a workbook that is provided to them by the Parkinson’s Voice Project (or, for people outside of the U.S, are given access to their eLibrary).
Treatment consists of 12 speech therapy sessions plus daily homework. Sessions are typically 45 minutes long, 3 times per week for 4 weeks.
What does a SPEAK OUT! Session Look Like?
- Warm-up vocalizations
- Sustained vowel production
- Pitch glides
- Reading (Words, phrases, sentences, and paragraphs of gradually increasing length and complexity)
- Cognitive exercises (Thinking + loudness. Patients often feel this is the most rewarding component)
- Discussion (How will you Speak with Intent today? More carryover, planning, and self- monitoring)
The Parkinson’s Voice Project created a follow-up program called LOUD Crowd. It’s a weekly group led by a speech-language pathology professional where SPEAK OUT! graduates can practice their exercises together.

It’s not a certification and doesn’t require renewal fees, unlike LSVT LOUD.
