🗣️ Speech Delay vs Autism — How to Tell the Difference?

A clear guide for parents, teachers, and clinicians

Not all children who speak late have autism. Some simply have speech delay, some have developmental language disorder, some have hearing impairments or excessive screen time, and some fall under the autism spectrum.

In India, most parents are told:
“Boys talk late.”
“TV de do, shuru ho jayega.”
“Woh sab normal hai, baad mein theek ho jayega.”

But precious years get lost while waiting. This article will help you understand the difference between speech delay and autism-related communication difficulties — and what steps to take early.

Understanding the Basics

Term What It Means
Speech Delay Child understands but has difficulty producing words or clear sounds.
Language Delay Child struggles to understand and/or express words, sentences, meaning.
Autism Spectrum Disorder (ASD) Child has delays in speech + poor social interaction + repetitive behaviours.
Selective Mutism Child speaks in some environments (home) but not in others (school) due to anxiety.
Hearing Loss Child doesn’t respond to name or sound → appears like autism or speech delay.

🛑 Is It Just Mobile Addiction or Autism?

(Very common confusion in Indian households)

🎯 Screening Tools for Parents & Doctors

Tool Age Type
M-CHAT-R 16–30 months Autism screening
CARS / ISAA 2–9 years Autism severity assessment
Receptive-Expressive Emergent Language Scale (REELS) 0–3 years Language development
Audiometry / BERA 6 months+ Hearing assessment

🛠️ What Should Parents Do First?

✅ Step 1: Hearing test (audiometry/BERA)
✅ Step 2: Child psychiatrist / developmental pediatrician evaluation
✅ Step 3: Start Speech Therapy + Occupational Therapy
✅ Step 4: Remove/limit mobile phones & TV
✅ Step 5: Home stimulation – talk, play, read, respond

👪 How to Stimulate Speech at Home (Practical Tips)

✔ Call your child’s name frequently
✔ Use gestures + words together (“bye-bye”, “come”)
✔ Read picture books, name objects
✔ Encourage imitation (clap, jump, touch head)
✔ Talk during daily activities (bathing, feeding)
✔ Reduce background TV/mobile completely
✔ Reward attempts at speech — do not shame mistakes

🌟 Hope for Parents

  • Speech delay is treatable, especially before age 5

  • Autism is manageable with therapy, early stimulation, and acceptance

  • Many children start speaking after consistent speech therapy + screen detox + parental involvement

  • Delay is not failure — delay without action is the problem
