Yeah but srsly I'm still feeling eased by their conservative claims that stutter can be mitigated but curing is very difficult(which means stutter is likely to relapse),not just accept my stutter unconditionally.I'm also a completely fluent speaker when I'm alone,speaking other languages and dialects except Chinese Mandarin.I'm a multilingual learner BTW and when I'm speaking French,Japanese and other Chinese dialects,I can warrant a 100% fluent speech. So your take makes a lot of senses and due to lack of decent and relible SLPs in the mainland of China,I haven't seeked any help for SLPs and I'm just trying to 'cure' my stutter(actually it's just blocks) on my own,searching over researches and turning to other knowledgable SLPs and PWS. Also I'm wondering if there are evidences that can show correlations between delayed successes in learning native language in babyhoods and stutter.
