One of the best English speaking courses for non-native speakers aiming to become fluent in conversational English is the “English as a Second Language” (ESL) course. ESL courses are specifically designed to help non-native speakers improve their English language proficiency in speaking, listening, reading, and writing.

Another popular option is the “TOEFL (Test of English as a Foreign Language) Preparation Course.” Although initially designed for test preparation, these courses focus on developing advanced English skills, including speaking fluency, which can benefit non-native speakers looking to improve their conversational English.

Additionally, many language schools and online platforms offer specialized conversational English classes tailored for non-native speakers. These classes usually focus on improving speaking and listening skills through interactive activities, role-playing, and real-life conversations.

Furthermore, immersion programs or language exchange opportunities where non-native speakers can practice English with native speakers in a real-life setting can also be extremely beneficial for developing conversational skills.

Overall, the best English speaking courses for non-native speakers are those that provide ample opportunities for practice, interaction, and feedback to help individuals become fluent in conversational English.
