Many test-takers struggle to achieve that magical 79+ in the PTE Speaking section. Because the Pearson Test of English is graded by an AI algorithm, you aren't trying to impress a human examiner; you are trying to satisfy a machine.
The AI relies heavily on two main parameters: Oral Fluency and Pronunciation. Unfortunately, many students unknowingly sabotage these metrics. Here are 10 common PTE Speaking mistakes you must avoid if you want to score 79 or higher.
1. Self-Correcting Your Mistakes
If you mispronounce a word or read the wrong word in Read Aloud, your first instinct is to stop and correct yourself. Don't do it. The AI heavily penalizes self-correction because it ruins your Oral Fluency. If you make a mistake, keep speaking as if nothing happened.
2. Speaking Too Fast
Many candidates confuse "fluency" with "speed." Rushing through your sentences causes you to skip syllables, blur words together, and lose your natural intonation. Speak at a moderate, natural pace.
3. The 3-Second Silence Rule
If you remain silent for more than 3 seconds, the microphone will automatically turn off, and you will not be able to record the rest of your answer. Always keep the audio flowing, even if you have to use a filler phrase in tasks like Describe Image.
4. Incorrect Microphone Placement
Breathing heavily into the microphone or placing it too close to your mouth causes "popping" sounds (especially on 'P' and 'B' consonants) that the AI cannot understand. Place the microphone parallel to your nose or chin, about two fingers away from your face.
5. Overcomplicating 'Describe Image'
The AI does not care how profound your analysis of the graph is; it only cares that you speak fluently about the key elements. Trying to understand complex data on the fly leads to hesitation. Stick to a proven template.
6. Faking a Native Accent
The PTE algorithm is trained to understand over 100 different accents. You do not need to sound British, American, or Australian to get a 90 in pronunciation. Focus on clarity and putting stress on the correct syllables, not on faking an accent.
7. Ignoring Punctuation in 'Read Aloud'
Reading a paragraph without pausing at commas or full stops makes you sound robotic. Use "chunking"—pause slightly at punctuation marks to mimic natural human speech and maintain proper intonation.
8. Using Filler Words (Um, Ah)
While humans naturally use "um" and "ah" when thinking, the PTE AI flags these as hesitations, which severely damages your Oral Fluency score. Practice replacing vocalized fillers with silent, micro-pauses.
9. Prioritizing Content Over Fluency in 'Retell Lecture'
If you miss a key point in the lecture, do not panic and freeze. In Retell Lecture, smooth delivery is often more forgiving than a choppy delivery packed with facts. Use your template to keep the rhythm going.
10. Shouting into the Microphone
Speaking too loudly distorts the audio clipping, meaning the AI will struggle to transcribe your words accurately. Speak at a normal conversational volume.
