The actual conversation process consists of two integral parts: listening and speaking. In my view it is expedient to master a conversation topic in English in the following sequence:

1. Learners listen to and pronounce each sentence of
English conversations (thematic dialogues and narrative texts with
transcripts).

2. Speaking on each conversation topic (imitation of
dialogues (role play), ready-made thematic questions and answers with
helpful content for using in daily life, narrations/telling stories, talking
points and discussions of issues).

3. Learning of additional conversation sentences and
vocabulary from English phrase books, conversation books and general
thematic English dictionaries that provide useful usage sentences.
Making up one’s own sentences with difficult vocabulary for potential
use in daily life.

4. Extensive reading of thematic texts and materials from various sources.
Telling the content of thematic texts.

5. Writing on real life topics.
My idea below may be important to you to improve your English materials.
As
you know word combinations (collocations) in speaking are
unpredictable. There are different word collocations/phrases and synonyms to
convey a thought in English. It’s possible to encompass in ready-made materials a
wide variety of English phrases for each conversation topic. It is a good idea to prepare a potential
list of phrases with sentences on each conversation topic, for example
fixed conversational phrases that do not require English grammar
knowledge (greetings, forms of addressing a person, thanks,
well-wishing, apology, agreeing, disagreeing, emotions, etc.). Practising
English with such materials can help a learner easier choose the most
appropriate word combinations to convey a thought. Multiple
frequent reading of such sentences in English will gradually ensure firm
memorisation of English vocabulary and contribute to developing good
speaking skills. By combining the
most inclusive English phrase books, conversation books, general English
thematic dictionaries, software, audio and video aids and websites you
can create the most practical and thorough content for mastering each
conversation topic in English for all levels including a wide selection
of ready-to-use phrases, vocabulary and sentences for daily use. Your own ready-made materials could be superior to (more helpful than)
any conversation book or a phrase book in terms of useful comprehensive
content and vocabulary. 

HOW TO PRACTISE ENGLISH LISTENING COMPREHENSION AND SPEAKING SKILLS.

In order to have good skills in listening comprehension in English and to speak it fluently, a learner should practise listening to audio and video aids in English (dialogues, thematic texts and narrative stories) with subsequent speaking. It is preferable to have English transcripts of audio and video material. I suggest that learners practise listening comprehension with subsequent speaking on a variety of topics and with materials for all levels on a regular long-term basis in the following sequence:

1. Listen to each sentence several times. Alongside listening see and read each sentence in the transcript.

2. Make sure you understand everything clearly in each sentence in terms of pronunciation, vocabulary and grammar.

3. Without looking into the transcript, try to repeat each sentence (say it aloud) exactly as you have heard it. Being able to repeat a sentence means that a learner has remembered its content.

4. Listen to that particular conversation or text (story) in short paragraphs or chunks, say each paragraph aloud, and compare to the transcript.

5. Listen to the whole conversation or story without interruption several times, and try to tell the content of the whole conversation or text (story) you’ve heard. You can write key words and phrases, or main ideas as a plan, or questions on that particular dialogue or text to
make easier for you to convey the content in English. It is important to compare what you’ve said to the transcript.

It is a good idea to record one’s speech on audio aid to compare it with the original audio/video recording. I believe that for practising listening comprehension and speaking in
English it is a good idea to include various practical topics for potential needs of learners with comprehensive vocabulary on each topic. As you know the content of materials matters a great deal. Ready-made thematic dialogues, questions and answers on conversation
topics, thematic texts (informative texts and narrative stories), grammatical usage sentences (in the form of dialogues and texts), and sentences with difficult vocabulary on various topics, especially with fixed phrases and idioms can be used in practising listening comprehension in English.

It’s possible and effective to practise listening comprehension and speaking in English on one’s own this way through self-check using transcripts, books, audio and video aids to provide additional solid practice and to accelerate mastering of English.
