Products, Sizes and Prices

We produce PronSci charts for use with students at all levels, and Silent Way charts for use with true beginners if the teacher is using the Silent Way methodology.


The set of PronSci charts simultaneously offer an analytic and a synthetic view of English pronunciation. They comprise

  • a Rectangle chart organised along articulatory lines,
  • a Spelling chart (also called a Fidel), which shows the complete relationship between sounds and spelling in English, and
  • sixteen Word charts containing the functional vocabulary of English organised by parts of speech.

The full set can be seen here.

The PronSci charts can be used alongside any approach for teaching grammar and vocabulary, and any textbook.

They are available for British and American English. The British charts are suitable for all varieties of English within the mute-r family (including RP, Australian, New Zealand and South African) and the American charts for all varieties found in North America (including General American and Canadian). This is possible because teachers can assign their own speech sounds to the colours.


The Silent Way charts exist for English, French and Spanish.


Sizes and Prices

The charts are sent from the UK. Many countries charge duties on imports. These have to be paid by the purchaser on receipt of goods.

(1) Classroom teaching

The charts are available in these sizes for English and these sizes for French, suitable for classrooms with more or less wall space and classes with different numbers of students. In general, we recommend using the largest size of chart that you can fit onto the wall space available.


If your wall space is limited, we would not recommend using the small set with more than 3 students, the medium set with more than 8 and the large set with more than 40. 


The charts are printed on a tough polyester canvas using matte inks, so they can be seen clearly even if hung where a poster would suffer from light reflection. They can be rolled for transport and storage. We normally print orders in a batch at the end of each month.

For English charts (PronSci or Silent Way), the prices for a set are as follows:

  Size of set
  Small £110  
  Medium £155   
  Large £215  
  Extra large     poa  


For French charts, a "set" is made up of a Rectangle chart, Word charts and your choice of Fidel (traditional or with silent endings).


If you wish to buy an additional Fidel or a Verb chart as part of the same order, the prices are shown to the right.

  Size of set
Price Price of additional Fidel Price of verb chart  
  Small £110 + £40 + £40  
  Medium £155 + £55 + £55   
  Large £215 + £75 + £75

(2) One-to-one Teaching and Home Tuition

When working with one (or at most two) students, the charts should be positioned vertically (off the table top), and within the student's reach to be able to point on the charts comfortably. (Wall space for the charts can be supplemented by using an artist's easel if necessary.)


The One-to-one sets are printed on card, with each Word chart at A5 size.


The price for an English set is £75.

The price for a French set is £75. An additional Fidel or a Verb chart cost an additional £20 each.

The price for a Spanish set is £45.


Postage and packing for a One-to-one set ranges from £10 to £40 depending on the destination. For currency conversion, click here. Please contact us to purchase sets.
