Language & Speech Basics - Tiny Talkers
- Speech: Motor production of sounds for communication.
- Language: Symbolic system (words, gestures) for meaning; receptive & expressive.
- Disorder Types:
- Articulation (sound errors, e.g., lisps)
- Fluency (flow disruption, e.g., stuttering)
- Voice (quality, pitch, loudness issues, e.g., hoarseness)
- Language (understanding/using symbols, e.g., DLD)
| Age | Expressive Language | Receptive Language | Speech Intelligibility |
|---|---|---|---|
| 6 mo | Babbles, coos | Turns to sound/voice | Vowel/consonant sounds |
| 1 yr | 1-2 words (mama, dada) | Follows 1-step command | Jargon, intonation |
| 2 yr | 2-word phrases, ~50 words | Points to body parts | ~50% |
| 3 yr | 3-4 word sentences, ~250+ words | Follows 2-step commands | ~75% |
| 4 yr | Tells stories, uses grammar | Understands "who, what, where" | ~100% |

Screening & Red Flags - Alarm Bells
Key alarm bells for prompt referral:
- No babbling by 12 months.
- No single meaningful words (e.g., "mama") by 18 months.
- Vocabulary < 50 words or no spontaneous 2-word phrases by 24 months.
- Speech unintelligible to unfamiliar listeners by 3 years.
- Any regression of language or social skills at any age.
- Persistent parental concerns about communication. 📌 Babbling absent by 12m, Words by 18m, Phrases by 24m → Refer!
⭐ Routine hearing screening is crucial in ALL children with suspected speech or language delay, as hearing impairment is a common reversible cause.
Key Disorders - Untangling Tongues

Key communication challenges:
- Articulation: Sound production issues (Phonological Disorder, Dysarthria).
- Fluency: Speech flow interruptions (Stuttering).
- Voice: Pitch, loudness, quality problems (Dysphonia).
- Language: Understanding/using language (DLD; or secondary to ASD, ID, Hearing Loss).
A closer look at common presentations:
| Disorder | Etiology | Presentation | Key Diagnostic Pointer |
|---|---|---|---|
| Articulation Disorder (Phonological) | Unknown; ?genetic, neuro factors | Difficulty producing speech sounds (e.g., "wabbit" for "rabbit"), omissions, substitutions. | Age-inappropriate sound errors; intelligibility affected. |
| Stuttering (Fluency Disorder) | Neurodevelopmental; genetic link | Repetitions (li-li-like), prolongations (sssssee), blocks, often with anxiety. | Disrupted speech fluency & time patterning. |
| Developmental Language Disorder (DLD) | Neurodevelopmental; strong genetic link | Persistent difficulty acquiring/using language (spoken, written). Reduced vocabulary, limited sentences, impaired discourse. | Language below age, impacts function; diagnosis of exclusion (not ID, ASD, hearing loss). |
Management Pathways - Guiding Voices
- Early Intervention: Cornerstone; initiate ASAP. Critical for neuroplasticity and optimal outcomes, ideally before age 3.
- Multidisciplinary Team (MDT): Involves SLP, pediatrician, audiologist, psychologist for holistic care.
- Speech-Language Pathologist (SLP): Leads assessment, diagnosis, and tailored therapy.
- Parental Counseling & Involvement: Key for home-based support, strategy implementation, and consistent progress.
- Prognosis: Variable; depends on disorder type, severity, intervention timing. Early, consistent support improves outlook.
⭐ Early identification and intervention are the single most important factors for a good prognosis in most language and speech disorders.
High-Yield Points - ⚡ Biggest Takeaways
- Speech vs. Language disorders: articulation/fluency/voice vs. comprehension/expression.
- Language delay red flags: no babbling (12mo), single words (18mo), 2-word phrases (24mo).
- Stuttering: common 2-5 years, most resolve spontaneously.
- Specific Language Impairment (SLI): language delay with normal IQ & hearing.
- Autism Spectrum Disorder (ASD): often has language & communication deficits.
- Rule out hearing impairment first in any speech/language delay.
- Early speech-language therapy is crucial for better outcomes.
