Parent question

How long does speech therapy take?

Published 21 October 2026 · Updated 21 October 2026

The short answer

There’s no standard length. ASHA leaves it to the speech-language pathologist (SLP) to decide based on each child’s progress, and studies of speech sound therapy that reported it ranged from about 3 months to almost 4 years from start to finish. How long it takes depends on the type and severity of the difficulty, how often therapy happens, and how much practice happens at home.

Typical patterns by type of difficulty

What research reports about therapy length
Difficulty	What studies report
Speech sound errors	Studies often used 30 to 60-minute sessions, 2 to 3 times a week. The 10 studies that reported total duration ranged from 3 to 46 months (Baker & McLeod, 2011). For R, see how long R therapy takes.
Late talkers	Parent programs are often short courses. Hanen’s It Takes Two to Talk, for example, has an orientation, 8 parent group sessions and 3 individual visits with the SLP.
Stuttering (preschool, Lidcombe Program)	The first stage took a median of 11 clinic visits in a UK study, longer for more severe stuttering (Kingston et al., 2003). The whole program, including maintenance, is designed to take one to two years (Sjøstrand et al., 2021).
Childhood apraxia of speech	Needs frequent, intensive therapy; children with severe apraxia may need it for years (NIDCD). Research supports at least twice a week, for at least 12 sessions (McCabe et al., 2026).

What affects how long it takes

Type and severity. In the stuttering study, more severe stuttering predicted longer treatment, and apraxia usually takes longer than a single sound error.
How often therapy happens. In a trial with the same 24 sessions, three a week led to more progress than one a week (Allen, 2013).
Practice at home. In ASHA’s outcome registry, children with severe speech sound disorders were more likely to make significant progress when sessions were combined with a home program (ASHA NOMS, 2024).
Real-world schedules. Research schedules are often more intensive than routine services: Australian SLPs reported delivering less intensity than research protocols use (Sugden et al., 2018).

How therapy ends

In schools, ASHA describes ending speech services as a team decision based on data, like progress toward goals and how the child communicates day to day. It isn’t automatic based on age or how long a child has had services.

Making the time count

Ask your SLP what the goals are for the next few months, and how often they’ll review them.
Do the short practice your SLP suggests between sessions. See practice at home.
Keep a simple practice log and bring it to sessions.

Questions parents ask

How many sessions will my child need?

There’s no standard number. It depends on the difficulty, its severity, how often therapy happens and how much practice happens at home. Your SLP can give you a sense after the first few months.

How long does it take to fix a lisp?

There’s no reliable average. Like other speech sound errors, it depends on the type of lisp, how often your child practises, and their age. See the S sound guide.

Why does school speech therapy seem slow?

School sessions are often less frequent than research schedules, and school SLPs have large caseloads. Practice at home can help fill the gap. See school vs private therapy.
