Pronúncia para ficar de olho
O falante usa 5 contrações e formas reduzidas, como don't, they're, you'll. Diga-as na forma curta, do jeito que você ouve.
- Os sons de “th”: smooth /smuːð/, ethereal /ɪˈθɪɚ.i.əl/, wither /ˈwɪðɚ/
- Os sons de “sh” e “zh”: transformation /ˌtɹæns.fɔɹˈmeɪ.ʃən/, parachute /ˈpæɹəʃut/
- Palavras longas — acerte a sílaba tônica: transformation /ˌtɹæns.fɔɹˈmeɪ.ʃən/, dandelion /ˈdæn.dəˌlaɪ.ən/, inflorescence /ˌɪnfləˈɹɛsəns/, ethereal /ɪˈθɪɚ.i.əl/, pollinator /ˈpɒlɪˌneɪtə(ɹ)/
Sons difíceis para falantes de português:
- Consoante final — sem acrescentar um “i” depois: seed /siːd/, globe /ɡloʊb/, clock /klɑk/, extend /ɛkˈstɛnd/, genetic /d͡ʒəˈnɛt.ɪk/
- /l/ final — a língua toca o céu da boca, não vira “u”: edible /ˈɛdəbəl/, curl /kɜɹl/, ovule /ˈɒvjuːl/, ethereal /ɪˈθɪɚ.i.əl/, unfurl /ʌnˈfɝl/
- s + consoante no início — sem um “i” antes: stem /stɛm/, stigma /ˈstɪɡmə/, smooth /smuːð/, snugly /ˈsnʌɡli/

- Faça shadowing frase por frase na velocidade normal, repetindo cada uma até o seu ritmo ficar igual ao do falante.
- Grave a sua voz e compare com o original, prestando atenção a palavras como ear, flower, seed.
O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
