With a speech-language professional, the learner reliably communicates one chosen need or fact to a partner using the preferred mode and a verification step.
This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.
Complete bounded explanation
What this power means.
Capability to develop or express communication recovery in a declared context without inheriting broader claims.
What the current evidence supports
Communication can improve or be effectively supported after neurological injury through multiple legitimate routes.
How to observe or measure it without overclaiming
Message success, participation, partner burden and person-defined communication matter alongside impairment tests; speech output alone is insufficient.
Myth
Restore speech and return to normal
Metric
Reliable message exchange, participation, fatigue and person-chosen modality
Boundary
More spoken words do not alone establish communication, cognition or autonomy.
Negative and limiting findings
The intensive-trial population and comparison interval were narrow.
No single modality fits all people or contexts.
Claims this evidence cannot support
restore normal speech for everyone
speech is the only real recovery
aphasia means reduced intelligence
AAC prevents recovery

How to learn this Power now.
With a speech-language professional, the learner reliably communicates one chosen need or fact to a partner using the preferred mode and a verification step.
Get readyThe speech-language professional selects the language/communication goal and screens hearing, vision, motor access, fatigue and consent.
Learn the method8 concrete steps teach the permitted method from start to finish.
See right and wrong5 comparisons show correct or safer execution beside common wrong or riskier choices.
PractisePractise a small set of meaningful messages at the frequency set by the SLP. Progress from known partner/topic to one changed feature at a time, while preserving AAC and other successful modes.
Check progressRecord correctly verified messages out of trials, missing meaning units, modality, partner prompts, time, fatigue and learner-rated usefulness.
Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. The method is Power-specific; its actionability follows this treatment.
Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.

Current teaching and evidence boundary
The next gate remains visible.
External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; a supervision or non-attempt boundary; cultural, community-rights or affected-person authority; a restricted safety or legitimacy boundary.
A Power-specific tutorial is available at /tutorials/pwr-061/. It contains a plain-English method, 8 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its supervised mode remains controlling.
