Aiuto con l'installazione di un pacchetto python

Buongiorno a tutti,
vorrei provare a cimentarmi un po' nell'ambito del riconoscimento vocale in Python e per prima cosa, come consigliatomi da alcune guide, ho installato speech_recognition. L'installazione non ha avuto intoppi ma quando mi sono ritrovato ad utilizzarla concretamente mi dava un errore ogni sua funzione. Mi diceva che era richiesto un certo PyAudio e subito ho provato ad installarlo ma ho ricevuto non pochi errori nell'installazione. Ho provato sia sul mio computer Windows che sul mio Linux e ho, in entrambi, ottenuto questo errore molto lungo:

Potreste darmi una mano e dirmi dove, io o il mio computer, stiamo sbagliando?

Grazie in anticipo
