Sabe a ultima palavra? então, agora está funcionando, mas o problema é que nessa ultima palavra não está tendo a sincronização correta, ela agora passa normalmente (que era o que eu queria) mas passa mais rápido, ou seja, não está considerando o tempo do arquivo srt.

Não sei se o problema é no cálculo do progresso para a última palavra. Ou se é na forma como o progresso está sendo aplicado à renderização da palavra.

Pense passo a passo e mande o código completo e corrigido.
