The study examined the ideologies embedded in the speeches of President Duterte on controversial issues using a qualitative design, mainly through a Critical Discourse Analysis of Fairclough. The material used was the ten speeches of Duterte from 2016-2019 that contained controversial topics. The study’s results revealed that his ideologies include negative representation, freedom of speech, social responsibility and good governance, transformational leadership, anti-corruption policy, liberal democracy, protection and security, public order and trust, civil service, and love for the country. These related beliefs and his policies form the basis of how he views things around him and the proper role of government in society as the Philippine president. By analyzing his language and the underlying meaning of his words and uncovering the ideologies underpinning discourse, people would get to know his beliefs, positions, and ideas in various matters, assisting them in interpreting issues, events, and conditions.

The qualitative study examined the discursive devices in President Duterte’s speeches on controversial issues using Critical Discourse Analysis. This study looked at ten controversial speeches given by President Duterte between 2016 and 2019, including a hardline stance against drugs and criminality, an end to graft and corruption in the government, a despotic policy against drug pushers, making brash off-the-cuff remarks, extreme bravery, stepped-up attacks against the rebels, and intense love for his country. The study results revealed that President Duterte used different discursive devices such as dysphemism, directness, alliteration, anaphora, metaphor, epiphora, and expressive values to evoke affiliative responses from his audiences, offend groups of people, give rhythm to the speeches, and emphasize, influence, encourage, and persuade others. The findings may be utilized further to provide valuable insight to the people to become good listeners and properly discern a particular discourse's real and fundamental meaning.
